Red Shell

“Throw a red shell, and it will zero in on the enemy!”

—Penguin, Super Mario Galaxy

Red Shells are red Koopa Troopa shells that frequently appear in various Mario games. They are the second most common shell, after Green Shells.

History

Super Mario series

Super Mario Bros. / Super Mario Bros.: The Lost Levels

The Red Shell's first appearance was in Super Mario Bros., where they are worn by Koopa Troopas. Red-shelled Koopa Troopas first appear in World 1-3; unlike the green-shelled Koopa Troopas, they do not fall off cliffs and simply turn around when reaching a ledge. Red Shells act in the same manner as Green Shells once kicked - they slide across the ground and defeating most enemies in its path until it is jumped on, goes far enough off-screen or falls down a pit. The player will be damaged if they are hit by the moving shell. Red Shells retain their color in all level environments.

In Super Mario Bros.: The Lost Levels, Red Shells and Green Shells reappear and retain their previous behavior.

Super Mario Bros. 2

Turtle Shells, or simply shells, are the only type of shells found in Super Mario Bros. 2, where they replace the blackface head-like objects known as "Big Face" (ビッグフェイス) from Yume Kōjō: Doki Doki Panic to avoid perceived racism. They are plucked from the grass and can be thrown - the Shell will slide forward, defeating most enemies it hits, until it makes contact with a wall and disintegrates. With some difficulty, it is possible to actually get on top of the shells and ride them.

Super Mario Advance makes them larger (and thus take longer to pluck). They are also more similar to regular Koopa Shells, as they rebound off walls instead of disappearing, and hurt the player if they touch the shell's sides; a heart also appears for each enemy it defeats.

Super Mario Bros. 3

Red Shells returned in Super Mario Bros. 3. They acted the same as in Super Mario Bros., but could now be carried and thrown, rather than just kicked. Super Mario Bros. 3 also introduces Giant Red Shells, worn by Red Giant Koopas.

Super Mario World

In Super Mario World, if Yoshi eats a Red Shell, he will spit out a trio of fireballs instead of the shell; Red Yoshi can use this ability from any shell color. Also, all Koopa shells can appear by themselves, including the Red Shell; stoping a Red Koopa Troopa out of its shell renders it a red Beach Koopa. A red or green Beach Koopa that enters a Red Shell becomes a Red Koopa Troopa.

Once Fall is unlocked by beating Funky in the original game, or by clearing all 96 exits in Super Mario World: Super Mario Advance 2, all Red Shells become red-colored Mario masks, but otherwise function the same; many instances of Red Shells and Koopa Troopas are also replaced with Blue Shells and Blue Mask Koopas, though red variants of each can still be found.

New Super Mario Bros.

Red Shells appear once again in New Super Mario Bros.; as in Super Mario Bros. 3, they can be carried and kicked around as usual after stomping the Red Koopa Troopa into retreating inside it.

Super Mario Galaxy

Red Shells reappear in Super Mario Galaxy as an offensive weapon. Like the Green Shells in the game, Mario can only hold the Red Shell, not ride it. If Mario throws a Red Shell near an enemy, it will home in on that enemy until it hits something. Underwater, it allows Mario to swim faster and with greater ease, and can also be thrown at underwater creatures to home in on them as well. Gold Shells also appear in this game, and act like Red Shells when thrown.

New Super Mario Bros. Wii

Red Shells reappear in New Super Mario Bros. Wii, where they act the same as in New Super Mario Bros.

New Super Mario Bros. 2

Red Shells reappear again in New Super Mario Bros. 2, where they retain their behavior from the previous game. If the player runs through a Gold Ring with a Red Koopa Troopa nearby, they will turn Golden; stomping them into their shell and kicking or throwing it produces a trail of coins behind the shell.

New Super Mario Bros. U / New Super Mario Bros. U Deluxe

Red Shells appear again in New Super Mario Bros. U and New Super Mario Bros. U Deluxe, where they retain their behavior from previous entries. Giant Red Shells also reappear.

Super Mario 3D World

In Super Mario 3D World, the standard green Koopa Shell turns red when Mario is inside it. Actual Red Shells appear in the second Boom Boom battle, where Boom Boom summons them to attack Mario and company while he uses his spin attack.

Mario Kart series

The Red Shell, as it appears in Mario Kart Wii

In the Mario Kart series, Red Shells (or Torpedo Shells) have the ability to home in on the opponent in front on the user. Red shells can be picked up in sets of one or three. Similarly to in Super Mario Bros. 2, Red Shells break on walls when they hit them. When the triple variant is used, three Red Shells rotate around the driver's kart upon usage, protecting them from Bananas and other shells (except in Mario Kart: Double Dash!!). If a driver collides with another driver while using Triple Red Shells, the other drive will be hit by one of the shells; if both drivers have a set of Triple Green Shells or Triple Red Shells, both are lost.

Triple Red Shells do not appear in Mario Kart DS Wi-Fi mode, as items cannot be equipped in that mode.

In nearly every game of the Mario Kart series prior to Mario Kart 8 Deluxe, Triple Red Shells were a player-exclusive item. One exception is in Mario Kart 7, where the AI is able to use Triple Red Shells if the "Shells Only" item setting is used. In Mario Kart DS, the AI can receive Triple Red Shells by stealing them from the player using Boo.

Red Shells make their first appearance in the Mario Kart series in Super Mario Kart. In this game, they travel straight towards the racer in front of the user, homing in on them without following the road. Unlike Green Shells, they can not be dropped behind the user and must be thrown forward.

In Mario Kart 64, single Red Shells are obtainable from 1st to 5th place. Similarly to in Super Mario Kart, Red Shells can only be thrown forward in this game, but will now follow the road to hit the target racer. In this game only, Fake Item Boxes can be used to block incoming Red Shells.e only

In Mario Kart: Super Circuit, single Red Shells can be laid behind the player and act as a land mine, chasing after the first kart that passes by, even the user.

In Mario Kart: Double Dash!!, the Triple Red Shells are a Special item exclusive to Koopa Troopa and Paratroopa (and Petey Piranha and King Boo, who can obtain any special item). Also, in Double Dash!!, the three shells are carried in their hands rather than circling around the kart. When the kart is hit by an item, they are left with a single shell.

In Mario Kart DS and Mario Kart Wii, red shells may hit the kart on the side rather than behind them, which prevents any items behind the kart from blocking it. In Mario Kart DS, single Red Shells are obtainable from 2nd to 6th place; in Mario Kart Wii, they are obtainable from 1st to 8th place, and will also slow down if the player they were targeting was hit by something else, speeding up once the player is vulnerable so it can hit them again.

In Mario Kart 7 onwards, Red Shells are able to trail in the sky, and enter launcher passages (such as Barrel Cannons) to pursue flying racers; in older Mario Kart games, Shells would simply fall when thrown in the air, and disappeared when they entered launching areas. In Mario Kart 7, they are obtainable from 1st to 5th place.

In Mario Kart 8 and Mario Kart 8 Deluxe, they follow the same rules as in past installments and can also come in singles or triples. However, Red Shells travel slower in the Deluxe version when they lock onto their target, allowing players to outrun them in 200cc. Triple Red Shells can also appear for AI in Mario Kart 8 Deluxe.

In Mario Kart Tour, Red Shells appear as an item, with only the single variant available.

The following gliders in Mario Kart Tour increase the chance of getting Red Shells and points for hitting racers with one.

Special skill	Normal	Super	High-End
Red Shell Plus	—	+20 points	+30 points

Mario Tennis series

Red Shells appear in the games Mario Tennis for the Nintendo 64 and Mario Power Tennis for the Nintendo GameCube and Wii. These Shells can be used during an Item Battle match, which can be obtained when the player hits an Item Box with the ball over the net. If the player hits the ball after receiving the item, a Red Shell comes out and chases the opponent.

In Mario Tennis Open for the Nintendo 3DS, a Red Shell is the emblem for the Shell Cup and appears on its trophy. A full tennis uniform-and-racket set with a design based on this item is available for Miis to use.

Yoshi franchise

Yoshi

A Red Shell makes a small appearance in the NES version of Yoshi after the player clears level 4 of the B-Type game, rewarding the player 400 points.

Super Mario World 2: Yoshi's Island / Yoshi's Island: Super Mario Advance 3

Red Shells appear in Super Mario World 2: Yoshi's Island, where they are worn by Red Koopa Troopas. Yoshi can stomp the Koopas out of their shell and then use his tongue to grab it and spit it out; it behaves as it does in the mainline Mario games, but cannot be eaten to make eggs.

Yoshi's Island DS

Red Shells and the Koopa Troopas that wear them reappear in Yoshi's Island DS, where they retain their behavior from Super Mario World 2: Yoshi's Island.

Super Smash Bros. series

Red Shells also appeared in the Super Smash Bros. series, and could be found in Super Smash Bros. and Super Smash Bros. Melee. Unlike the Green Shell, which went in a straight path until it fell off, the Red Shell will stay on one platform and slide back and forth, hitting anyone who steps on that platform (including the user) before disappearing after a short time.

Paper Mario: Sticker Star

Red Shells appear in Paper Mario: Sticker Star as the shiny variant of Green Shells. Also, every Paratroopa in the game has a Red Shell on its back.

Mario & Luigi series

Mario & Luigi: Partners in Time

In Mario & Luigi: Partners in Time, the Red Shell is a Bros. Item that can be used to damage enemies. The brother that chooses the item will kick the Shell towards a foe; once it hits them and bounces off, it will slide towards the other bro, who must press their corresponding button to kick it back. Like the Green Shell Bros. Item, the Red Shell can be kicked back repeatedly, and moves faster with each kick. Unlike the Green Shell, it will automatically target a new enemy if one is defeated; it can also land more than 16 hits, and can be kicked indefinitely until one of the brothers misses or all enemies are defeated.

When the adult and baby Mario brothers fight together, the babies can sit on the shell; pressing their button upon hitting the enemy will perform a spin that increases damage for each hit.

Mario & Luigi: Dream Team

3D Red Shell in Mario & Luigi: Dream Team

The Red Shell reappears as the first of Mario's Bros. Attacks in Mario & Luigi: Dream Team, under the name 3D Red Shell. It costs 4 BP to use. The Attack Pieces to obtain the 3D Red Shell are found in Mushrise Park, and are required to proceed through the game. It can only target enemies on the ground like its counterpart, the 3D Green Shell, but will automatically target a new enemy if the targeted one is defeated.

Upon selecting the attack, Mario and Luigi will run into the foreground, where Mario will take out a Red Shell. Pressing has him kick it at one of the enemies; after it hits and rebounds, the player must then press to have Luigi kick it back, and alternate between them for each kick. After the Red Shell hits nine times, Luigi will then spin the Red Shell towards Mario to blast it at their foe for the tenth and final hit; if all enemies are defeated before the attack ends, it will end prematurely.

Striking three, five, nine and ten times with the Red Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.

Mario & Luigi: Paper Jam

3D Red Shell in Mario & Luigi: Paper Jam

The 3D Red Shell returns in Mario & Luigi: Paper Jam, functioning the same as it did in Mario & Luigi: Dream Team. However, the move is now available from the beginning of the game, costs 3 BP instead of 4, and deals considerably more damages at the cost of being shortened to six hits. The speed of both the shell and the Bros. moving forward is also increased.

Striking one, three, five and six times with the Red Shell will yield an "OK!", "Good!", "Great!" and "Excellent!" rating respectively.

Mario Party series

Mario Party 3

A Red Shell appears in Mario Party 3 in the minigame Ridiculous Relay. The first player in the group rows it using an oar.

Mario Party 9

Red Shells appear in Mario Party 9 in the Goomba Bowling minigame, where players must throw them at the Goombas.

Mario Strikers series

In the Mario Strikers series, the item works very similarly to the Green Shells in those games. However, they home in on nearby opposing players instead of sliding in a given direction; in the event it misses a targeted player, it will bounce around the stage like a Green Shell. They are also obtainable in groups of three, similar to the Mario Kart games, as well as a Giant variety. Red Shells are generally useful when clearing room for a Super Strike, a Mega Strike, or a Skillshot.

Mario & Sonic series

Mario & Sonic at the Olympic Games

Red Shells appear during the Dream Race event in the Nintendo DS version of Mario & Sonic at the Olympic Games. The shells function similarly to those in the Mario Kart series, homing in on an opponent and causing them to lose speed if they are hit, although their effect can be blocked if the player is using a Shield. The shells also appear in Dream Long Jump, where they also cause the player to lose height, though they can be blocked by using a Shield or Starman. They appear in the Dream Canoe event with a similar function; the player who manages to hit another competitor with a Red Shell steals three of their coins. They come in sets of three, and can be avoided or blocked by using a Starman item.

Red Shells perform an almost identical function during the Dream Race in the Wii version, where they can be thrown forward and home in on opponents, causing them to lose speed when hit; they can be dodged using a Starman, invincibility from a Chaos Emerald or by jumping over them. Red Shells also appear as items in Dream Platform, where they will home in on an opponent and destroy any Brick Blocks between it and the target, and can be blocked by using a Barrier.

Mario & Sonic at the Olympic Winter Games

In the Nintendo DS version of Mario & Sonic at the Olympic Winter Games, Red Shells appear as items in Ski Cross Racing, Rocket Ski Jumping and Extreme Snowboarding, where they can be thrown forwards or backwards and will home in on the opponent closest to the player in that direction. Being hit by a Red Shell causes the character to lose speed and Rings in Ski Cross Racing, but can be blocked using a Barrier or Super Star; in Rocket Ski Jumping they will lose speed, height and energy, but can block the Red Shell using Super Stars and Barriers. In Extreme Snowboarding, the character is only knocked over when hit, but can block Red Shells using Super Stars and Barriers.

In the Wii version, Red Shells appear as items in Dream Alpine, Dream Ski Cross, Dream Snowboard Cross, Dream Short Track and Dream Bobsleigh, where they will home in on the opponent in front of the player and slow them down if they hit, but can be defended against using Shields and Super Stars. Red Shells also appear as an item in the Individual version of Dream Ski Jumping, where they will home in on an opponent and cause them to lose height, speed, 10 points and a Bonus panel if they are hit, but can be defended against using a Barrier. Red Shells also appear as items in Dream Curling, where they turn the curling stone into a Red Shell that homes in on the pins when thrown until it comes to a standstill. In the Individual and Team versions of Dream Gliding, Red Shells home in on the nearest opposing character and will knock them out of the sky if hit.

Mario & Sonic at the London 2012 Olympic Games

In the Wii version of Mario & Sonic at the London 2012 Olympic Games, Red Shells appear as an item in several London Party minigames.

In the Nintendo 3DS version, the Red Shell and Green Shell appear on a badge that can be obtained from the badge machine.

Mario Sports Mix

Red Shells also appear in Mario Sports Mix. When used normally, they'll chase after an opponent and temporarily knock out anyone in their path. When combined with a ball or puck, the object will travel a curved path at high speeds that can throw off opposing players.

Appearances in other media

In Monopoly Gamer, a Red Shell face is on the "Power-Up Die". A player who rolls the Red Shell normally can force any other player on the board to drop three Coins on their current space, which can be picked up by the next player who passes over or lands on that space. Some characters have a "Power-Up Boost" that enhances or changes this power.

In Animal Crossing: New Leaf, Triple Red Shells appear as special furniture that can be obtained randomly from fortune cookies. When interacted with, they continuously play the Red Shell alarm from Mario Kart DS. In Animal Crossing: Pocket Camp, a single Red Shell can be obtained as a reward for catching five Eep Cheeps in Fishing Tourney #12, which began on March 14, 2019 as part of the Super Mario crossover event for Mario Day.
