This is a list of glitches in the game New Super Mario Bros.
Glitches
NOTE: Unless otherwise noted, all names are conjectural.
Above the Ceiling
In the several towers of the game, the player must fight Bowser Jr.. Like most enemies, the player can jump off of him at great height while holding 
. This can be exploited, as most of the arenas where Bowser Jr. is fought do not have walls going past the upper boundary. With a well-timed jump, the player can reach this out-of-bounds ceiling area. This glitch can be further broken if Mario or Luigi jump off of Bowser Jr.'s head at the final hit. Bowser Jr. will play his usual animation, but the silhouette of Mario or Luigi's head closes into the corner Mario or Luigi are in.
Behind the Flagpole
To perform this glitch, the player must go to World 1-1 and go to the end of the level. Mario/Luigi must go up to the flagpole, but run to the wall on the other side and wall jump. This causes him to land on the flagpole, but as soon as he touches it he is flung to the other side of the flagpole. The flag goes down, but then flips over to Mario.[citation needed]
Bowser Jr. Death by Falling
In World 5-Tower, the player should get to the boss. Then, they must walk to the edge while Bowser Jr. charges at them. If done correctly, Bowser Jr. charges off the platform. Then the screen zooms out to show an empty area. The only way to escape is to fall off the platform. Once the player loses a life, the screen shakes and teleports them to the map.[citation needed]
Caged
This glitch can be done on multiplayer mode. The host must choose the underground level, and Player 1 must go to the pile of Brick Blocks to the right of the red Koopa Troopa. Player 1 should ground pound the third vertical row of brick blocks, without pounding the last brick that makes Mario fall in the bottomless pit. Player 2 should grab the star while Player 1 ducks inside the vertical row of brick blocks they previously pounded. If done correctly, Player 1 ends up inside the pile of brick blocks.
Challenge Mode Out of Bounds
The player should have challenge mode active. In any level where there is a wall down from the ceiling, if there is the right amount of space between the edge of the screen and the ceiling, the player should jump into it. The player will be standing on nothing. If they keep jumping up to the ceiling, they will be pushed through to the right until the wall ends. This is easiest achieved in World 1-2 at the start of the level.
Continuous Boss Music
In World 8-
Bowser's Castle, if the player defeats Bowser first, then defeats Bowser Jr., the final boss music continues to play.
Die while Invincible
This glitch requires very precise timing and is best done in multiplayer. One player must be without any power-up and the other must carry a Bob-omb. The first must collect eight Coins to get a Star, and the second must throw the Bob-omb at them when they are about to collect the Star. If done correctly, the first player dies while having the effect of the Star, even if the animation is stopped.
Disappearing Bandana
When fighting Bowser Jr. with his bandana over his mouth, the player must wait until he throws a Green Shell at them. They must jump on the shell and grab it. When he hides in his shell, the player has to throw the shell at him, and Bowser Jr. appears without his bandana.
Falling Skull
To do this glitch, the player must be playing World 1-
Tower. They must go to the place with the first Star Coin and jump on the Dry Bones so its skull tumbles onto the one-way platform. Then, as the moving platform moves down, the skull will fall through the floor.
Floating P Switch
If the player finds a P Switch atop a breakable Brick Block and breaks the block, the P Switch will not fall and remain floating in midair. This glitch must be performed in a form other than Small Mario or Mini Mario in World 4-A. This does not work in World 5-C strangely enough.
Frozen Bowser Jr.
The player needs to enter a Bowser Jr. battle where he does not wear his bandana, and have a Mega Mushroom in stock. When the player is in the battle and activates it and stands still, Bowser Jr. will be flipped over when he touches Mario or Luigi. If the player waits until they turn back to normal and jumps on Bowser Jr., the jump will not do anything. The only way to attack him is to do a ground pound.
Frozen Ghost House
Playing as either Mario or Luigi in World 4-
Ghost House, the player should jump onto the very left/right of one of the spin dials and immediately jump straight off it. If done correctly, the whole room will freeze. The player can smash blocks but only the first frame of their animation will play out.[1] The player can also fire fireballs but they freeze too. If the player goes on the spin dial properly or touches an enemy, the level switches back to normal.
Frozen Lakithunder
In World 7-
Castle, the player should have a Blue Shell while fighting Lakithunder. In his first phase, they must hit Lakithunder two times with the blue shell before he flies up. If done correctly, Lakithunder should be frozen in place.[2] The only way to beat him is to stomp on him or use the shell spin attack.
Goomba in the Air
The player must have a Mega Mushroom in their inventory and be in World 4-Castle. Just before they battle Mega Goomba, they need to activate the Mega Mushroom and walk/jump to the right to trigger the cutscene. If done correctly, the Goomba will walk in mid-air. After the cutscene, the battle will start as normal. This glitch will be harder to trigger after the first time it is performed unless the player scrolls the camera to the right.
Jump on Switch
The player should jump on a switch and immediately jump again. If done correctly, the player will not activate the switch, or the switch is activated while the player jumps off it.
Level Music Glitch
If the Starman effect ends just as Mario or Luigi reach a level goal, the level music plays while Mario/Luigi slide down the pole. The song stops when the Course Clear fanfare starts. This glitch is easy to do in World 1-1 if the player gets the Starman in the secret block in the middle of the level.
Mini Mario Wall Jump Glitch
When the player is wall jumping as Mini Mario, Mini Mario will sometimes jump from an invisible platform the size of a pixel after jumping from another wall.
Mega Mushroom Storing Trick
When the player finds a Mega Mushroom in a level (1-1, 1-2, 4-4 and 7-5), they must let the Mega Mushroom run to any unbreakable Block (empty ? Block, empty Brick Block, etc.). The player must jump into the Mega Mushroom and in the Block on the same frame. If done correctly, the character will not transform, and the Mega Mushroom appears in the player's Item Storage.[3]
Muted Boss Music
To perform this glitch, the player must have a Mega Mushroom in their inventory. In World 4-Castle, when they are fighting Mega Goomba, the player should use the Mega Mushroom to become Mega Mario, but not kill Mega Goomba. When the effect of the Mega Mushroom runs out, the boss music will not play.
Power-Ups Through Stairs Glitch
The player should go to World 3-Ghost House with any power-up in storage. Then, they should activate the first set of stairs, stand under them and release the power-up. The power-up will fall down slowly through the stairs.
Reusable Mega Mushroom
The player must bring a Mega Mushroom to World 3-Castle. Upon reaching a Whomp, the player should allow it to fall, and the player should stand on top of the enemy without defeating it. Next, the player should drop the Mega Mushroom and grab it while standing on the Whomp. Mario becomes Mega Mario, destroying the Whomp, but there is not enough space to fully transform and the player re-obtains the Mega Mushroom. This allows it to be re-used to defeat enemies without using up the Mega Mushroom, but the ceiling must be low enough so the Mega Mushroom can be stored again.
Starman Jump Effect
The player should get a Starman, and go into a pipe just as the Starman wears off. As soon as the character comes out of the pipe, they should immediately jump, and the character should be jumping as if still under the effect of the Starman, even though they're not invincible.
Stomp while Giant
In multiplayer mode, there is a slight possibility that a player under the effect of the Mega Mushroom stomps the other (like normal) when they jump on them instead of just hurting it. This seem to happen random and the causes are unknown.[citation needed]
Stuck above Bubble
Mario or Luigi must need a Blue Shell for this glitch to work. In World 8-3 the player must go into the pipe to get underwater. Then, they must go above the center of the bubble to the right. If done correctly, Mario or Luigi will be stuck bouncing on the bubble and hitting the ceiling.[4]
"Stuck" Between Blocks
This glitch can only be performed in World 1-4. The player must have a Mini Mushroom in their backup, then must play the level normally up to point where the Koopa Troopa is needed to break the formation of blocks. They must wait until the Koopa Troopa kills itself and drops down to the lower two blocks left. On the right block, they must Ground Pound and Jump, and should hit a hidden block (the player might go through the wall if they time it right). Then, they must use the Mini Mushroom and jump above the left block. The player becomes be "stuck" inside the two blocks.
Swing Glitch
This can be done in World 7-1 in the part with the swings and where the second Star Coin is. If the player jumps off the top swing and jumps onto the cloud on the right side of it they become stuck in the swing position. The only way to stop the glitch is to fire a fireball (or jump if player is Super).
Through the Ground
In World 1-Tower, if there is a flying ? Block, the player has to hit the block so that its top is one pixel above the blue platform. Then they must jump on the empty block and walk towards the center of the platform, possibly going through the platform. If not, the player can try again by jumping at the block and walking to the middle again.
Through the Wall
For this glitch, Mario/Luigi must go to World 5-B. He should be at least Super Mario/Luigi and duck and jump at the very beginning. He becomes slightly trapped in the Ice Blocks. If he quickly jumps again, he goes through the wall. This can used to get the secret exit without a Blue Shell.[5]
Trapped
This glitch happens in World 4-Ghost House, and Mario or Luigi need a Mega Mushroom in the character's item slot. They should go to the place where the "Frozen Ghost House" glitch happens (the "room" with the single Boo and invisible blocks in it), and go into the next room (the one that is barren except for a Balloon Boo and a one-way platform). To start the glitch, they should apply the Mega Mushroom and go onto one of the objects that takes the player go to the next room "properly". Their head becomes stuck in a pipe. They cannot move horizontally, but they should attempt to jump to start the glitch. Mario or Luigi are unable to jump, and they are taken back to the previous room. To fully activate the glitch, they should jump off and the spin dial will go the previous room. All they can do now is exit the level, or if they haven't completed the level, the player should wait for time to expire.
Under the Flagpole
In World 2-5, the player should use challenge mode for this glitch. The player should have any power-up (excluding the Mini Mushroom). The player should go through the level until the player sees a Boomerang Bro. The player should then go to the right of where it was, and jump into the quicksand. The player must keep hold of right on the D-pad while the player is sinking. When the player starts to move, Mario or Luigi should still be keeping hold of right, then the player must press . Mario or Luigi appear in a place that has gray blocks behind them, as they have to go down. The player should go on a Blockhopper. The player must jump when they are near the ceiling near a Star Coin. The player must keep jumping until they're stuck in a rock. The player is then at the end of the level, and under the flagpole. The player should jump when they are not moving, causing them to go past the flagpole.
Walk On the Ceiling
If the player has challenge mode enabled, then go to World 6-1. In the beginning of the level, the player notices that the mountain ceiling does not start for a few blocks. Mario should inch forward until the amount of free space shown on screen is just a bit too small for Mario or Luigi to jump into. After that, Mario should go to the far left of the screen and wait for the Bill Blaster to shoot. The player must on the Bullet Bill and enter the thin gap of space that they have created. If it worked, Mario stands in mid-air in the gap. Once Mario is there, the only thing he can do is jump again, and keep jumping until he has gone far off the top of the screen. Once Mario has jumped enough, he is be able to move again, above the level. Mario can then run to the end of the level, and he does not even fall back when there is open sky. Mario cannot run backwards due to the fact that challenge mode has to be on. In the end, the player has to wait for time to run out, since there is no way to get back, or the player has to return to the map.
Walking Backwards oversight
In the World 4 map, after unlocking a green Toad House, the player can put Mario or Luigi in the overworld map on 4-1 and press down on the D-pad. The player now walks backwards until they reach the turn in the path.
Walking in Midair
In World 4-6, the player should go up to where there are three green pipes on a rock above, each with a Piranha Plant. The player should stay there and wait for Dorrie to leave. The player should wait until the time has reached in the 140 mark. Mario or Luigi should go to the far left, but not on the ledge. The player should run and jump, and, if the player is far enough, Mario or Luigi should be walking in the air. However, when the player gets to the pipe, Mario or Luigi are teleported to somewhere, become invisible and unable to move.
