'''''Super Mario World 2: Yoshi's Island''''' (frequently referred to simply as '''''Yoshi's Island''''') is a 2D [[Genre#Platform games|platform game]] for the [[Super Nintendo Entertainment System]], developed by [[Nintendo Entertainment Analysis and Development|Nintendo EAD]]. The game is the prequel to ''[[Super Mario World]]'', and it stars [[Yoshi]] and the [[Yoshi (species)|Yoshi clan]] who, while carrying [[baby Mario]], travel across [[Yoshi's Island (location)|Yoshi's Island]] to rescue [[baby Luigi]] from [[baby Bowser]] and his [[Magikoopa]] minion/caretaker, [[Kamek]]. Instead of relying on [[jump]]ing and a power-up system for combat as in the traditional ''Super Mario'' platformers, Yoshis use their tongue and eggs to overcome obstacles, as well as the introduction of many other different mechanics. The game is notable for introducing a time-based health system rather than hit points, an anomaly to what many platform games typically did in this game's time period. Rather than relying on powerful pre-rendered graphics just like its contemporary ''[[Donkey Kong Country]]'', ''Super Mario World 2: Yoshi's Island'' employs a very distinct, stylized arts and crafts style to stand on its own. The game makes use of the Super FX2 graphics chip (one of only four commercially released SNES games to do so), which allows for larger, more detailed sprites and more advanced effects that emulate 3D space.

Although ''Super Mario World 2: Yoshi's Island'' was not as financially successful as its predecessor, the game's highly positive reception and unique style have spawned [[Yoshi's Island (series)|a new series]] of platform games from the ''[[Yoshi (franchise)|Yoshi]]'' franchise, although it is the fourth entry overall. The game has received various adaptations into manga, such as receiving volumes dedicated to it in the ''[[Super Mario-kun]]'' and [[Super Mario (Kodansha manga)|Kodansha's ''Super Mario'' manga series]] and extensive [[List of merchandise|merchandising]]. This is the only ''Yoshi's Island'' game to be released on a home console. The game has received a [[Reissue#Remakes|remake]] on the [[Game Boy Advance]], ''[[Yoshi's Island: Super Mario Advance 3]]'', which was released on [[Virtual Console#Nintendo 3DS|Virtual Console]] for the [[Nintendo 3DS]] (with owners applicable for the [[Virtual Console#Nintendo 3DS Ambassador Program|Nintendo 3DS Ambassador Program]] being able to download the game for free) and [[Wii U]]. The original SNES version of ''Super Mario World 2: Yoshi's Island'' is included on the [[Classics#Super NES Classic Edition|SNES Classic Edition]], and although it was never announced for release on Virtual Console on any other system, it is one of the 20 launch titles for [[Super Nintendo Entertainment System - Nintendo Switch Online]] on the [[Nintendo Switch]]. A sequel, ''[[Yoshi's Island DS]]'', was released in 2006 for the [[Nintendo DS]]. In 2014, the [[Nintendo 3DS]] game ''[[Yoshi's New Island]]'' continues the story told from the first game.

'''From the first cinematic of ''Super Mario World 2: Yoshi's Island'':'''
<blockquote>
Narrator: ''A long, long time ago... This is a story about [[baby Mario]] and [[Yoshi]]. A [[stork]] hurries across the dusky, pre-dawn sky. In his bill, he supports a pair of twins. Suddenly, a shadow appears in a gap between the clouds and races towards the stork with blinding speed.''<br>
Kamek: '''''"SCRREEEECH!!!"'''''<br>
Kamek: '''''"THE BABIES ARE MINE!"'''''<br>
Narrator: <i>'''WOW!!!''' Snatching only one baby, the creature vanishes into the darkness from whence it came. The second baby falls undetected towards the open sea... '''OH NO...'''<br>
Meanwhile, here is [[Yoshi's Island (location)|Yoshi's Island]], home to all [[Yoshi (species)|Yoshies]]. It's a lovely day, and [[Yoshi]] is taking a walk. '''HUH?!?''' Suddenly, a baby drops in onto his back. The baby seems to be fine. This is very fortunate! Wha-? Something else fell with the baby... Let's take a peek... It looks like a map. Maybe the stork was using it? But Yoshi can't figure it out. Yoshi decides to talk to his friends.</i><br>
Kamek: '''AAAAAAAAAAKK!!!'''<br>
Narrator: <i>[[Kamek]], the evil [[Magikoopa]], and kidnapper of the baby, quickly dispatches [[Kamek's Toadies|his toadies]], when he discovers that he missed the other baby!<br>
Yoshi heads leisurely back to the other Yoshies, unaware of the danger at hand. Kamek's forces are actively searching the island. Will these two children ever reach their parents safely?</i>
</blockquote>
'''From the second cinematic of ''Super Mario World 2: Yoshi's Island'':'''
<blockquote>
Narrator: <i>This paradise is Yoshi's Island, where all the Yoshies live. They are all in an uproar over the baby that fell from the sky. Wait! The baby seems to know where he wants to go... The bond between the twins informs each of them where the other one is. The Yoshies decide to carry the baby to his destination via a relay system. Now begins a new adventure for the Yoshies and baby Mario.</i>
</blockquote>
'''From the instruction booklet'':'''
<blockquote>
''This story happened a long time ago...this is a story about a baby and Yoshi...''<br>
''A stork hurries across the dusky, pre-dawn sky. In his bill, he supports a pair of twins, who are to be delivered to their parents as soon as possible.''<br>
''Suddenly, something appears between the clouds and races towards the stork with blinding speed!''<br>
''"SSCCRREEEEECH!!!", it screams. "These babies are mine!"''<br>
''Snatching only one baby, the creature vanishes into the darkness from whence it came.''<br>
''Oh no! The second baby falls undetected towards the open sea...''<br>
''The kidnapper is Kamek, an evil Magikoopa from the Koopa Kingdom. Having divined last night that twin babies born this morning will bring disaster to the Koopa family, he arranged for an early morning ambush. Returning to his castle, Kamek realizes that he missed the other baby. He orders his toadies.''<br>
''"Go forth and find that other baby! Don't let his parents get him back! Ever!!"''<br>
''Meanwhile, the second baby does not fall into the sea after all...it lands safely on Yoshi's back! And right after him drops a map!!''<br>
''This paradise is Yoshi's Island. And on this island lives lots of different Yoshies. These Yoshies are naturally laid back and relaxed, but this a calamity and everyone is in a state of panic. As the Yoshies frantically yell over each other, the baby insistently points at something.''<br>
''Yes! The baby can sense the other baby's location. All the Yoshies quickly agree to help carry the baby to its destination by using a relay system not unlike the old pony express.''<br>
''The Green Yoshi draws first honors.''
</blockquote>

The story of ''Super Mario World 2: Yoshi's Island'' takes place while Mario and Luigi are in their infancy, referred to as baby Mario and baby Luigi respectively. A stork was about to deliver the newborn twins baby Mario and baby Luigi to their parents, but is ambushed by Kamek on the way there. While Kamek was successful at capturing baby Luigi and the stork and imprisons them at Bowser's Castle, baby Mario plummets into the sea, only to find himself on a Yoshi's back on an island. The Yoshis then discover that baby Mario also has a map with him, which reveals the location of Bowser's Castle. Kamek has then figured out that he has missed baby Mario and then has dispatched his Toadies to kidnap baby Mario. While the Yoshis discuss what to do with baby Mario, baby Mario then notifies the Yoshis which direction to go due to a powerful twin link, where the Yoshis then employ a relay system to transport baby Mario across the island. After overcoming obstacles and fighting bosses that Kamek has enlarged in various forts and castles in the island, the Yoshis finally manage to defeat Kamek and baby Bowser and rescue baby Luigi and the stork, allowing the stork to safely deliver the babies to their parents.

==Gameplay==
[[File:Yisland3.png|thumb|left|Yoshi aiming his egg at one of the enemies.]]
Like the early titles of the [[Super Mario (series)|''Super Mario'' series]], ''Super Mario World 2: Yoshi's Island'' is a two-dimensional, side-scrolling platform game. In addition to the typical run and [[jump]] controls, the Yoshis can also catch enemies and manipulate objects using their tongue. After catching an enemy, the Yoshi can either spit out or swallow them, although if Yoshi keeps an enemy in his mouth long enough, he eventually swallows it (with the exception of enemies he can only hold and spit out and not swallow). Swallowing most enemies allows the Yoshi to lay a [[Yoshi's Egg|Yoshi Egg]], which it can carry up to six of; eating another enemy results in the egg at the front of the line to be discarded. While Yoshi has some eggs, the player can aim with a constantly moving target reticle and throw them to damage enemies, activate objects, ricochet them off solid surfaces, and skim them across water. This reticle can be locked into one position while aiming, and while Yoshis are aiming their eggs, they can still move around and jump. While most eggs come in green, some are yellow and red, and they release coins and stars when shattered respectively. While a Yoshi throws an egg, the egg changes color depending on how much it has bounced off walls. Green eggs can bounce up to three times, yellow eggs bounce only twice, and red eggs bounce only once. Power-ups also exist in the form of [[morph bubble|metamorphosis bubble]]s, which allow Yoshi to transform into various forms, and the [[Super Star]], which lets baby Mario turn into [[Superstar Mario|Powerful Mario]]. In addition to these moves, Yoshis can use [[Flutter Jump|Hovering Jump]]s multiple times in the air to increase the distance they travel. The first Hovering Jumps can increase the height of the jump, but subsequent Hovering Jumps mostly serve to prolong the duration of the fall. Yoshis can [[Ground Pound|Pound The Ground]] to smash stakes and defeat certain types of enemies. Camera controls include looking up to see upper areas of the level and ducking to force the camera down.

[[File:Yisland1.png|thumb|Yoshi about to free baby Mario from his bubble imprisonment.]]
''Super Mario World 2: Yoshi's Island'' introduces the concept of time-based health, a mechanic that is reused in future ''Yoshi's Island'' games. When the Yoshi comes into contact with an enemy, baby Mario becomes separated from Yoshi, encased in a bubble and floating around in the air. While baby Mario is in this state, a [[Countdown Timer]] appears, counting down in seconds until it reaches zero, in which time Yoshi must recover baby Mario or [[Kamek's Toadies]] take baby Mario, and the player loses a life. The Timer starts at ten seconds at the beginning of each level, and can be increased to a maximum of thirty by collecting [[Star (Yoshi's Island series)|Star]]s, using [[10-Point Star|10 Point Star]]s and [[20-Point Star|20 Point Star]]s, and entering [[Checkpoint Ring|Middle Ring]]s. If the Timer falls below ten, it increases back up to ten slowly after recovering baby Mario. Entering a Middle Ring also marks the point where the Yoshi can continue from if it loses a life. Other ways Yoshis can lose lives are if they touch spikes or thorns, if they fall off a cliff, if they touch lava, if they get eaten by a Lunge Fish, or if they get crushed by moving platforms. In these cases, Yoshi's death is shown onscreen, either by spinning and collapsing or flying offscreen. If the player runs out of lives, they receive a [[Game Over]].

There are six worlds in this game, and each world has nine levels total. The objective of each level is to reach the [[Goal Ring]] roulette. There are ten spots on the roulette, and five of the spots can be made winning spots by collecting the five [[Smiley Flower|Special Flower]]s in each level. Landing on one of the flower points allows the player to play a [[Bonus Challenge]]. These Bonus Challenge allow Yoshis to either gain lives or [[Special Item (Yoshi's Island series)|Special Item]]s for use in levels. Two levels in each world are forts and castles, and the goal in those levels is to reach and defeat the eponymous boss that resides in those establishments rather than reach a Goal Ring. Most bosses are regular enemies that are enlarged by Kamek prior to the fight, with a few exceptions.

Scattered throughout each level are three types of collectibles: thirty Stars, twenty [[Red Coin|red coin]]s, and five Special Flowers. At the end of each level, the player's score is tallied with a maximum of 100 points, with flowers worth ten points each and red coins and Stars one point each. Attaining a perfect one hundred points in all eight levels in a [[world]] unlocks a [[Bonus Challenge]] and an "extra" ("special" in Japanese) level on the level selection map. The extra levels are designed to be more difficult than any other level in the game, and each one has its own unique gimmick. However, the player can always choose to exit an extra level by pausing the game and pressing {{button|snes|select}}; in other levels, this can be done only if the level in question has already been cleared.

If the player succeeds in attaining a perfect one hundred points in the extra level of a world, a Star is added to the top of the title screen the next time the player turns on the game, for a maximum of six Stars.

===Controls===
[[File:Yisland4.png|thumb|200px|The option mode for the control settings.]]
There are two controller configurations: Patient and Hasty. By default, Patient is selected. The control setup can be swapped at any time on the world map by scrolling over to the button with the Super Nintendo controller next to the "Score" option and selecting it; additionally, at some points, there are [[Message Block]]s that allow the player to swap control configurations. The only difference between the "Hasty" and "Patient" settings is that with "Patient" the player must press {{button|snes|A}} to target and press it again to throw an egg, while with "Hasty" the player must hold {{button|snes|A}} to target and release it to toss an egg.

The setting of the game takes place on [[Yoshi's Island (location)|Yoshi's Island]], which is the first world setting of ''Super Mario World''. The island portrayed in ''Super Mario World 2: Yoshi's Island'', however, is much larger in scale and comes with a larger variety of biomes and characters endemic to the island as players progress through the game. The game contains six worlds with eight regular levels each, retaining the eight level per world structure first normalized by ''[[Super Mario Bros. 3]]'', having a consistent amount of levels per world, and every fourth and eighth level of the world features a boss fight against an enemy enlarged by Kamek. All worlds have particular themed biomes, such as [[World 1 (Super Mario World 2: Yoshi's Island)|World 1]] having a grasslands while [[World 6 (Super Mario World 2: Yoshi's Island)|World 6]] has a stronger theme around caverns and lava as the player closer approaches [[King Bowser's Castle]]; this theming of levels has been carried in further entries of the ''Yoshi's Island'' series. Unlike ''Super Mario World'', ''Super Mario World 2: Yoshi's Island'' does not employ use of a world map and relies on a level select screen, which is represented by color-coded folders containing icons that preview the levels, and these levels are named after their features than rather than using generic numbered identifies, such as the third level of World 3 being called [[Nep-Enut's Domain]] rather simply being called World 3-3. One notable aspect of the level icons is that all Yoshis in their previews are Green Yoshis, despite Green Yoshis being used only in the first levels of each world, the Extra levels and King Bowser's Castle. While most levels have players moving on their own accord, a few levels are autoscrollers, with the first one being encountered in [[Hop! Hop! Donut Lifts]] in World 1.

Every world contains an unlockable level known as an Extra levels, which are unlocked when players get a 100 score in all levels of the worlds. These levels feature a gimmick and are shorter and more difficult than other levels of the game, often do not contain [[Checkpoint Ring|Middle Ring]]s and they are optional to complete in regards of general progression of the game. These levels do not feature unique icons that display a preview of the level and are instead represented by a star with a number and identifier. In addition, when players first play the game, they play through a level called [[Welcome To Yoshi's Island]], which serves as a short tutorial guiding players basic controls of the game. Once completed, it cannot be replayed, effectively making it an [[Unrevisitable area|unrevisitable area]].

Due to the light arts and crafts aesthetic of the game and usage of the Super FX2 graphics chip, levels and their backdrops are rendered reminiscent of drawings rather than the more organic approach that ''Super Mario World'' has done, and their backdrops are dynamically rendered with a more complex palette. For example, the primary backdrop for [[Watch Out Below!]] from World 1 uses a soft palette and hills having an emulated colored pencils aesthetic, clouds and hills contain visible shading streaks to communicate their shadows, environment features such as waterfalls and crystals in cave levels such as [[The Cave Of Chomp Rock]] and [[The Cave Of The Mystery Maze]] are animated, [[Goonie Rides!]] renders a shimmering ocean with a large flock of the [[Goonie]] species and variants flying in the background, while the general aesthetic of World 6 primarily uses warm color palettes to communicate players that the world is lava-themed and the final world of the game.

==Characters==
===Playable characters===
The Yoshi species are the primary playable characters of the game and this appearance is their first starring appearance in a platformer title. All Yoshis play identically to each other, and ''Super Mario World 2: Yoshi's Island'' introduces even more color variations to the Yoshi species: in addition to the Green, Red, Blue and Yellow Yoshis that are present in ''Super Mario World'', Pink, Light Blue, Purple, and Brown Yoshis are introduced. While Pink, Light Blue, and Purple Yoshis become mainstay colors in future installments of the overall ''Super Mario'' franchise, Brown Yoshis remain exclusive to this title, being replaced by Orange Yoshis. The Yoshis in this game retain their long tongues and their abilities to eat most objects from ''Super Mario World'', though the game introduces [[Flutter Jump|Hovering Jump]]s, turning enemies and objects into eggs that can be used as projectiles, and [[Ground Pound|pounding the ground]].

The Yoshi colors are specific to the levels they are played on.

|}

{{footnote|note|a|The Yoshis' positions on the map screen are swapped, with the Pink Yoshi at the seventh level and the Red Yoshi at the second. This was corrected in the Game Boy Advance version.}}

===Supporting characters===
While ''Yoshi'' games prior feature adult [[Mario]] in a starring role while Yoshi accrues a more passive role, such as ''[[Yoshi (game)|Yoshi]]'', ''[[Yoshi's Cookie]]'', and ''[[Yoshi's Safari]]'', ''Super Mario World 2: Yoshi's Island'' and further entries in the ''Yoshi's Island'' series flips the roles in which the Yoshis are the primary, controllable stars while Mario, as baby Mario, rides on Yoshis and acts as their timed health meter should they get hurt by enemies or objects. Baby Mario is directly controllable only under the effects of the Super Star as [[Powerful Mario|Superstar Mario]] where he dons a yellow cape and becomes invincible. [[Luigi]] makes his debut in the overall ''Yoshi'' franchise as baby Luigi, though his role mirrors [[Princess Peach]] of the ''Super Mario'' franchise in that he is kidnapped and the overall goal of the game is to rescue him from [[Kamek]] and [[baby Bowser]]'s clutches.

Two supporting characters are introduced in ''Super Mario World 2: Yoshi's Island'' and make recurring appearances throughout the ''Yoshi'' franchise. The [[stork]], designed after the {{wp|white stork}} representing an animal of folklore known to deliver babies to parents, gets ambushed and kidnapped alongside baby Luigi at the start of the game. The latter character [[Poochy]] is a dog-like creature that follows Yoshi around and Yoshi can ride on who can run on dangerous terrain such as lava and spikes.

====Helpers====

===Bosses===
[[File:RaphaelTheRavensCastle2.png|thumb|200px|Yoshi fighting the boss of World 5, Raphael the Raven.]]
Each world features a midway fort (the fourth level) and an end-world castle (the eighth level) with a mid-boss and a big boss respectively. Every boss is just an enlarged version of a basic enemy that [[Kamek]] super-sizes with his magic. The only exception is [[Froggy]], who remains at his normal size while Yoshi and baby Mario are shrunk; he then eats them and the battle is located in his stomach.

Big Baby Bowser attacks by sending flying rocks, breathing fireballs at Green Yoshi, and charging into Green Yoshi. He is defeated when Green Yoshi hits him seven times. If Big Baby Bowser gets too close, he destroys the platform Green Yoshi is standing on, defeating Green Yoshi.

==Transformations==
===Metamorphosis bubble===
Entering a [[morph bubble|metamorphosis bubble]] causes Yoshi to be transformed into one of several different types of vehicles, each with their own unique capabilities. While in this state, Yoshi is allowed to move around as the vehicle without baby Mario for a limited time before being pulled back to the metamorphosis bubble and being turned back to normal. If the player is able to hit a [[Yoshi Block]] while transformed, the transformation is automatically reversed at that location.

==Minigames==
===Bonus Challenge===
[[Bonus Challenge]]s are initiated when the Goal Ring stops on a flower at the end of the level. Yoshis can increase the chances of playing a Bonus Challenge by collecting Special Flowers on the level. During a Bonus Challenge, the player players one of several minigames. Upon winning the minigame, the player can receive lives or [[Special Item (Yoshi's Island series)|Special Item]]s. A specific Bonus Challenge is unlocked when the player collects 800 points in a world, and that specific Bonus Challenge can be played any time.

There are six Bonus Challenges in total.

===Mini Battles===
[[Mini Battle]]s are minigames that can be played in various levels, when a Yoshi receives a key and enters a Bonus Game Shack. These are competitive fights against a Bandit, and besting that Bandit earns the Yoshi a reward. Mini Battles can later be played in the main level selection screen after they have been unlocked. If the players hold {{button|snes|select}} and press {{button|snes|X}}, {{button|snes|X}}, {{button|snes|Y}}, {{button|snes|B}}, and {{button|snes|A}} on the level selection screen, a screen pops up listing all Mini Battles, as well as a 2-player version of Throwing Balloons and Watermelon Seed Spitting Contest and a 4-button Throwing Balloons mode.

There are four Mini Battles in total.

==Soundtrack==
{{main|Super Mario: Yossy Island Original Sound Version}}
A soundtrack CD was released in Japan on November 25, 1995, titled ''Super Mario: Yossy Island Original Sound Version''. The disc contains 26 music cues from the game's soundtrack, as composed by [[Koji Kondo]].

The instrumentation for this game's music was sampled from the {{wp|Akai S1000}} synthesizer; {{wp|E-mu Systems}}' {{wp|E-mu Proteus|Proteus}} synthesizers; the {{wp|Korg 01/W}}; Optical Media International's Universe of Sounds Vol. 2; {{wp|Roland Corporation|Roland}}'s L-CD1 synthesizer, {{wp|Roland Sound Canvas|Sound Canvas SC-88}} module, and {{wp|Roland R-8|R-8}} drum machine; and the {{wp|Yamaha Corporation|Yamaha}} TG77 and TG100. The Roland Sound Canvas, in particular, would go on to become one of the longest-used sources of instrumentation in ''Super Mario'' franchise music, with samples from both the SC-88 and the later {{wp|Roland SC-8850|SC-8850}} model being used in numerous games during the next four gaming generations. Some of the game's sound effects are samples of stock sound effects: the jungle ambience heard on the title screen and baby Mario's cry are taken from {{wp|Sound Ideas}}' General Series 6000 library, while Yoshi's tongue sound and the noises made by Piranha Plants come from Rarefaction's ''A Poke in the Ear with a Sharp Stick''.<ref>https://docs.google.com/spreadsheets/d/1JJBlHHDc65fhZmKUGLrDTLCm6rfUU83-kbuD8Y0zU0o/edit?pli=1#gid=717751203</ref>

==Promotion==
===Culver City event===
[[File:CulverCityYoshisIsland.jpg|thumb|150px|Flyer promoting the Culver City event.]]
An event was held in front of a Toys "R" Us in {{wp|Culver City, California}} on October 5, 1995 at 3:00 PM to promote the North American release of ''Super Mario World 2: Yoshi's Island''. At the event, there was a trailer and a large model [[Yoshi's Egg|Yoshi Egg]] surrounded by hay. The trailer held a banner with the words "Play It Loud" and stock art of ''Super Mario World 2: Yoshi's Island''. The Yoshi Egg held a banner with the word "Nintendo". The event centered around "hatching" the Yoshi Egg. After the hosts interacted with the idle audience, children were lined up and given small, green hammers which they used to break open a designated area at the bottom of the egg. The Yoshi Egg, when breached, yielded stringed paper and a large model of the game cartridge. Group photos were then taken of children with the cartridge.

The organizers of the event also pledged to donate five hundred dollars to local schools on the condition that the principals of these schools sit on top of the Yoshi Egg for fifteen minutes. A person in a one-piece Mario and Yoshi costume also was seated on top of the Yoshi Egg. Participants could go on and off the egg by means of a forklift.

A raffle was then held with one winner receiving an SNES which included a copy of ''Super Mario World 2: Yoshi's Island''. Other winners may have won t-shirts. Discount coupons were also distributed.

===Videos===
[[File:A Magical Tour of Yoshi's Island VHS.jpg|thumb|The ''A Magical Tour of Yoshi's Island'' VHS.]]
Nintendo of America distributed ''Super Mario World 2: Yoshi's Island: A Magical Tour of Yoshi's Island'', a six minute-long promotional VHS. The video featured Ken Lobb and the same person who narrated the ''[[Donkey Kong Country#Trivia|Donkey Kong Country: Exposed]]'' promotional VHS.

Another promotional video, titled ''The Invasion of Nintendo'', was included with a copy of ''Nintendo Power'' and featured ''Super Mario World 2: Yoshi's Island'' alongside some other Nintendo games. Ken Lobb made another appearance.

There exists another untitled promotional video that was likely shown on monitors in video game stores. It is about fifty seconds long and consists of clips of the game along with some narration.<ref>https://www.youtube.com/watch?v=WKzA-SCjnG4</ref>

==Adaptations==
The adaptation of ''Super Mario World 2: Yoshi's Island'' is covered in [[Super Mario-kun Volume 14|volumes 14]] and [[Super Mario-kun Volume 15|15]] of ''[[Super Mario-kun]]''. It begins with the original "Koopa Empire" arc from [[Super Mario-kun Volume 13|volume 13]], in which Mario, Luigi, and Yoshi are transported to a future where Bowser triumphed. After stopping his reign, Bowser decides to go back in time and prevent Mario from ever being born. The three follow him with a time machine and, after rescuing Baby Mario from Kamek's clutches, not trusting the hungry Yoshis, they take Baby Mario with them and goes to rescue Baby Luigi, all the while Bowser and Kamek are trying to stop them. In this version, Baby Bowser is absent: Bowser from the future takes his role after a [[POW Block]] shrinks him to a baby size during the last chapters.

In the [[Super Mario (Kodansha manga)|Kodansha ''Super Mario'' manga series]], a three-volume miniseries titled ''Super Mario: Yoshi Island'' was also released. The first two volumes are based on the stories from the game, while the end of the second volume and the third have an original follow-up story arc about Yoshi and the Baby Mario Brothers founding the [[Yossyi Helper Team]] to stop Baby Bowser's mischievous plans.

''Super Mario World 2: Yoshi's Island'' was also adapted as part of the ''[[4koma Gag Battle]]'' series, also titled "''Super Mario: Yossy Island''". 

An issue from the Game Picture Book series of the [[Super Mario Ehon]] series, ''Super Mario Game Picture Book 4: Hang in There, Yoshi'' (「スーパーマリオゲームえほん 4 がんばれヨッシー」, ''Super Mario Game Ehon 4 Ganbare Yoshi''), is loosely based off the story of ''Super Mario World 2: Yoshi's Island''.

==Staff==
{{main|List of Super Mario World 2: Yoshi's Island staff}}
''Super Mario World 2: Yoshi's Island'' was directed by video game designers [[Takashi Tezuka]], [[Shigefumi Hino]], and [[Hideki Konno]] and programmer Toshihiko Nakago; the four had worked on previous titles in the ''Super Mario'' series, with all except Hino being directors for ''[[Super Mario World]]''. Konno had earlier worked as a map and level designer in the previous ''Super Mario'' games and served as map director for ''Super Mario World''. This is the first ''Super Mario''-related project to involve [[Yasuhisa Yamamura]], who has most notably worked on the dungeon design in the ''[[zeldawiki:The Legend of Zelda (Series)|The Legend of Zelda]]'' series. The C.G. design the game employs is credited to [[Yoshiaki Koizumi]], who previously worked on ''[[Super Mario Kart]]'' as the illustrator. The soundtrack was composed by [[Koji Kondo]], well known for creating the ''Super Mario'' franchise's iconic tunes. [[Shigeru Miyamoto]] had heavy involvement with the game's development and served as the game's producer, while Nintendo's then-president, [[Hiroshi Yamauchi]], was the executive producer.

==Development==
In an interview with game journalist Steven Kent, Shigeru Miyamoto stated that he wanted to make a game starring Yoshi as far back as ''[[Super Mario World]]''{{'}}s development.<ref name="History"></ref> Miyamoto disliked previous ''Yoshi'' games (specifically mentioning ''[[Yoshi's Cookie]]'', ''[[Yoshi (game)|Yoshi's Egg]]'', and ''[[Yoshi's Safari]]'', the latter being mistranslated as "''Yoshi's World Hunters''" in the interview) and wanted to make one more authentic to the Yoshi character.<ref name="History"></ref>

An early version of the game was demoed to [[Nintendo]]'s marketing department, who rejected it due to the visuals "lacking punch" in comparison to ''[[Donkey Kong Country]]''{{'}}s pre-rendered 3D graphics.<ref name="History">''The Ultimate History of Video Games: The Story Behind the Craze that Touched our Lives and Changed the World'', p. 518.</ref> In response, [[Shigeru Miyamoto]] developed a more stylized and "cartoony" art direction for the game, which was accepted. Some of the pre-rendered sprites used in the opening of the game are leftovers from the original graphical pitch.

According to Hisashi Nogami, the hand-drawn style was created by literally drawing the characters by hand on paper, scanning them and then carefully copying them to make the sprites "a pixel at a time".<ref>[https://kotaku.com/how-yoshi-s-island-got-its-beautiful-hand-drawn-look-1826849563 Kotaku, "How Yoshi’s Island Got Its Beautiful, Hand-Drawn Look"], 2018-06-15</ref>

''Super Mario World 2: Yoshi's Island'' was one of three completed games to use the Super FX2 graphics chip, which allowed for larger sprites and more advanced effects such as sprite scaling and rotation (advertised as "Morphmation" technology), basic polygonal rendering, and advanced parallax scrolling.

==Reception==
===Critical reception===
''Super Mario World 2: Yoshi's Island'' was critically acclaimed upon release, with most reviews praising the level design, the platforming mechanics, the personality, the graphics, the soundtrack, and the creativity of the game. The game remains critically lauded, garnering a 96.00% on GameRankings based on 5 reviews.<ref>[http://www.gamerankings.com/snes/588740-super-mario-world-2-yoshis-island/index.html GameRankings score]. ''GameRankings''. Retrieved March 1, 2018.</ref> The most common criticisms surrounding the game come from baby Mario's crying when he is trapped in a bubble after Yoshi takes a hit from the enemy, often being cited as "annoying". IGN retrospectively said in its article "Is There a Bad Mario Game?", "The game earned instant acclaim and rightfully so for its brilliant stage design and platforming mechanics. Yoshi's Island doesn't beat you over the head with trial and error to teach you how to play, but it also does not hold your hand with a numbingly dull tutorial."<ref>(February 13, 2009) [http://www.ign.com/articles/2009/02/13/is-there-a-bad-mario-game?page=2 "Is There a Bad Mario Game?"] ''IGN''. Retrieved March 1, 2018.</ref> Kaes Delgrego of Nintendo Life has referred to the game as "Perhaps the greatest platformer of all time" in his review, giving the game a score of a 10/10.<ref>Delgrego, Kaes. (July 22, 2009). [http://www.nintendolife.com/reviews/2009/07/super_mario_world_2_yoshis_island_retro Review: Super Mario World 2: Yoshi's Island] ''Nintendo Life''. Retrieved March 1, 2018.</ref> Delgrego called the time-based health mechanic "innovative" for its time and described it as influention on later titles, comparing it to ''Halo''{{'}}s time-based life mechanic. While he admitted that the game itself isn't revolutionary, Delgrego praised the creativity of its puzzles and pastel-style graphics. Delgrego's only criticisms focused on the easy boss fights and baby Mario's crying when Yoshi takes damage from an enemy. Reece Warrender of Cubed3 gave the game a 9/10,<ref>Warrender, Reece. (March 31, 2006) [http://www.cubed3.com/review/412/1/super-mario-world-2-yoshis-island-snes.html Super Mario World 2: Yoshi's Island (Super Nintendo) Review] ''Cubed3''. Retrieved March 1, 2018.</ref> praising the game's new and interesting mechanics, such as swallowing an enemy to create a projectile of it, as well as having simple and enjoyable mechanics that players of any age can enjoy. Warrender praised the quality of the game's graphics and sound while criticizing the easy difficulty and the short length, citing that the game can be completed in five hours despite the replay value of the points system.

Retrospective reviewers often rank ''Super Mario World 2: Yoshi's Island'' as one of the greatest video games in the medium's history. Among others, the game was placed 18th in the 100th issue of [[Nintendo Power]]'s "100 best Nintendo games of all time" in 1997. It also placed 185th in the 200th Issue of [http://www.gameinformer.com/ Game Informer's] "Top 200 Games of All Times", the lowest ranked ''Super Mario'' franchise game. Tony Mott listed the game in the 2013 revision of his reference book ''1001 Video Games You Must Play Before You Die'', making it one of 26 SNES games to be featured, while IGN included ''Super Mario World 2: Yoshi's Island'' in the 2003, 2005, 2007, 2015, 2018, 2019, and 2021 lists of the top 100 video games of all time.

According to Shigeru Miyamoto, the marketing department at Nintendo wanted him to use pre-rendered 3D sprites like in ''[[Donkey Kong Country]]'' for the game, rather than stylized 2D sprites. Additionally, found in the game's data are several sprites that go unused, such as several ''[[Super Mario All-Stars]]'' sprites and three unused Yoshi forms. There are also three unused Mini Battles that can be seen in the game's code. 

The game was originally intended to feature the prefix '''''Super Mario Bros. 5''''', which was shortened to ''Super Mario'' in the final Japanese release. A similar concept would be carried over to the international edition, which uses the prefix ''Super Mario World 2''; the original ''Super Mario World'' was previously subtitled ''Super Mario Bros. 4'' on the Japanese release.<ref>Brian (July 24, 2020).

===Giant Egg anywhere===
By going into any level with a [[Fat Guy]] and carrying a [[Giant Egg]] to the end of a level, the player must go to the edge of the screen past the exit and throw the egg up, then use Yoshi's tongue to push it slightly into the edge of the screen. By finishing the level like this, the next Yoshi will collect the egg as it appears to take baby Mario, allowing the player to take a Giant Egg into any level in the game.<ref name="SOAG">[https://www.youtube.com/watch?v=kLn2FqOhvFQ Super Mario World 2: Yoshi's Island Glitches (SNES) - Son Of A Glitch - Episode 37].

==Remakes and ports==
[[File:Super Mario Advance 3 Box Art.jpg|thumb|Box art for the Game Boy Advance version of the game.]]
===''Yoshi's Island: Super Mario Advance 3''===
{{main|Yoshi's Island: Super Mario Advance 3}}
''Super Mario World 2: Yoshi's Island'' was later ported to the handheld [[Game Boy Advance]] as part of the [[Super Mario Advance (series)|''Super Mario Advance'' series]], a series of updated remakes of classic ''Super Mario'' games, as ''[[Yoshi's Island: Super Mario Advance 3]]''. The third entry in the series, it boasted new levels and slightly altered some of the original game's graphics and dialogue, as well as making various other minor changes. This version of the game is the only version available through the Virtual Console on future consoles, rather than the original version.

===SNES Classic Edition===
''Super Mario World 2: Yoshi's Island'' is one of the 21 titles included on the [[Super Nintendo Entertainment System#Super NES Classic Edition|Super NES Classic Edition]]. This was the SNES version’s first release since the original run.

===Super Nintendo Entertainment System - Nintendo Switch Online===
''Super Mario World 2: Yoshi's Island'', along with ''[[Super Mario World]]'' and ''[[Super Mario Kart]]'', is one of the 20 launch titles for [[Super Nintendo Entertainment System - Nintendo Switch Online]].

==Version differences==
{{main-wiki|TCRF|Super Mario World 2: Yoshi's Island/Version Differences}}
Later versions of the Japanese release pluralize the collectables in the score screen and alter the number of dots that connect each term to its respective counter. The line in the Red Coin counter is increased by one dot, while the line in the total score counter is decreased to account for the pluralization of "Total Point."

===Regional differences===
*This is the first first-party ''Super Mario'' game with French and German localizations. (Some third-party games, such as the [[Mario is Missing! (PC)|PC]] and [[Mario is Missing! (Super Nintendo Entertainment System)|SNES]] versions of ''Mario is Missing!'', were localized in French and German earlier.) Accordingly, the PAL release gives the player the option to select a language at the start of the game.
*The title screen in the Japanese version of the game is rendered in katakana. International versions replace this with a new logo written in English.
*The European release omits the ® symbol from the ''Super Mario World 2'' prefix on the title logo.
*In the map selection screen, the thumbnail tiles for the extra levels in the Japanese versions of the game are a red and orange background. They are also called "Special" stages.
*In the Japanese release, the thumbnails for extra and bonus stages consist of stylized katakana logos; the extra stages all read スペシャル ("Special") and are suffixed by the world number, while the bonus stages each list the name of their respective bonus game. In international releases, the extra stage thumbnails depict a numbered star with "EXTRA" written below, while the bonus stage thumbnails depict a numbered Special Flower with "BONUS" written below.
*The score thumbnail in international versions of the game has a completely different sprite than Japanese versions of the game, depicting a pencil drawing a line rather than a pencil writing "100" on an index card. The SNES controller in the North American version of the game also has its buttons changed to purple, though the control options menu retains the multicolor buttons seen on the Super Famicom and European SNES.
*The thumbnail for the [[Popping Balloons]] Mini Battle is slightly tweaked in international versions of the game, rounding the balloon down at the edges of the thumbnail and increasing the size of Yoshi's hands.
*The thumbnail for World 4-6: [[Lake Shore Paradise]] has a slightly altered Flopsy Fish in international versions of the game, featuring larger and more angular pectoral fins.
*In the European version, as well as US Revision 1.1, the font is much thicker than in the Japanese version, though graphics such as controller buttons were left the same. This thicker font was later used in all versions of ''Yoshi's Island : Super Mario Advance 3''.

}}

*International versions of the game remove onomatopoeia words from the chalkboard tutorial graphics and the Popping Balloons Mini Battle. Additionally, the symbol that appears when popping the correct balloon in the latter is changed from the kanji 当 ("win") surrounded by stars to a star pattern made of stars.
*In World 6-★: [[Ultimate Castle Challenge|Castles - Masterpiece Set]], the pathed-moving platforms in the Japanese version of the game spelled out "YOSSY", Yoshi's alternate romanized Japanese name. International versions change this to "YOSHI".

==References to other games==
*''[[Mario Bros. (game)|Mario Bros.]]'': [[POW Block]]s can be hit thrice before they disappear, like in this game.
*''[[Alleyway]]'': [[Breakable block]]s are featured in some levels, and are broken in a similar manner to the ones in the game.
*''[[Super Mario Bros.]]'': The end of the credits features a rearranged version of this game's "end of level" fanfare. [[Fire Bar]]s return, albeit depicted as swinging three-dimensionally.
*''[[Super Mario Bros. 2]]'': [[Shy-Guy]]s and [[Snifit]]s reappear; these enemies also serve as the basis for many of the new enemies in ''Super Mario World 2: Yoshi's Island''. The sub areas attached to enemy-generating [[Warp Pipe]]s resemble those within [[Jar]]s. POW Blocks retain their color scheme from this game.
*''[[Super Mario Bros. 3]]'': [[Chain Chomp]]s, [[Donut Block]]s, and [[Nipper Plant]]s return. [[Spike]]s return as [[Spike#Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3|Mace Penguins]].
*''[[Super Mario World]]'': The American and European title of the game suggests a connection to ''Super Mario World''. Also, some of Yoshi's sound effects are reused. [[Expansion Block]]s utilize an unused sound effect from this game when they expand. [[Big Boo]]s, [[Unshelled Koopa Troopa|Beach Koopa]]s, and [[Fishin' Lakitu]]s return. [[Flying Wiggler]]s are based on [[Wiggler]]s. A single [[Magikoopa]] returns as [[Kamek]], whose name is derived from the name for the Magikoopa species in Japanese:「カメック」(Kamekku). [[Gargantua Blargg]]s and [[Blargg (small)|Red Blargg]]s are named after [[Blargg]]s. [[Cheep Cheep#Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3|Piscatory Petes]] resemble the [[Cheep Cheep]] design of ''Super Mario World'', along with the [[Blurp]]s of the same game. [[Superstar Mario|Powerful Mario]] wears [[Caped Mario]]'s cape. [[Dotted-Line Block]]s temporarily transform into [[! Block]]s upon hitting a [[! Switch#Yoshi franchise|Switch]], like how they could be transformed by the [[! Switch#Super Mario World / Super Mario World: Super Mario Advance 2|big switch]]es of this game. [[Lakitu's cloud]] can be ridden, like in this game.
*''[[Yoshi's Cookie]]'': Yoshi's sprite is based on his sprite from the SNES version of the game, which was also the basis for his sprite in ''[[Super Mario All-Stars]]''.

==References in later games==
[[File:The Beach Cannons Secret.png|thumb|The background shares a similar artstyle]]
