List of Super Mario Maker 2 glitches

This is a list of glitches from Super Mario Maker 2.

Glitches
NOTE: All names are conjectural unless otherwise specified.

Black Hole
NOTE: This glitch has been partially patched.

The method to perform this glitch differs between the Super Mario 3D World and other styles. In said style, first the player should stack seven horizontal Warp Pipes, then place Big Bloopers on each pipe, and copy-and-paste them five times. Next, they should place a vertical pipe with coins and stack it four times, copy-and-paste that stack eight times, then copy-and-paste single vertical pipes until they reach the object limit. The player must then pull out the Bloopers from the horizontal pipes, erase the pipes, and undo until all Bloopers are back to the previous position. If done, the Bloopers will remain horizontal. The player should repeat this on the all of the other stacks, then delete all of the vertical pipes. The player should then overlap Blooper stacks on top of one another until they form into one Blooper. This causes terrains such as pipes, Spike Blocks, and ! Blocks to overlap, and the ground to connect incorrectly. This can also be done with Stingbies.

In any other game styles, the glitch involve tracks, Hard Blocks, and a Big Thwomp. First, the player should place a Hard Block on a track, then copy-and-paste it until the hundredth track is placed. The player should then erase one of them, then place another track with a Big Thwomp. The player then must copy one of the tracks with a Hard Block, and drag the track with the Big Thwomp downwards. The Big Thwomp will be placed incorrectly; the player must undo it. If done, the Big Thwomp will act as if it is still on the track. Next, the player must erase all of the tracks with Hard Blocks, and overlap the Big Thwomp repeatedly. This also causes Fire Bars, Wigglers, Twisters, and Arrow Signs to overlap.

An alternative way to do this glitch was discovered afterwards, which still can be performed on the version 1.1.0, and can be done with all of the game styles. In all game styles besides Super Mario 3D World, the player should firstly place tracks until they reach the limit, then delete two tracks and place a Big Thwomp. The rest follows the same method as above.

In the Super Mario 3D World style, first, the player should overlap a ? Block and track in 2D game styles, then put a coin into the ? Block, then drag and move the track leftwards, which causes the track to become invisible. The player should then save the course and reload it. The "Corrupt data was found so the course has been deleted." message will be shown, so the player should select a new file in the same spot. The player should repeat this if the starting style is one one other than the Super Mario 3D World style. If it is, the player must select the undo option once. This causes an invisible track to appear in the style, and the player must perform the same method as above until the Big Thwomp is placed on the track. The player should drag the track upwards until it reaches the limit and overlap the Big Thwomp as explained above.

This glitch can also be used to lift 3D World-exclusive elements to the other styles and vice versa, including the Moon, which causes the night effect in all level themes except Underground and Desert, such as floating Goombas and 1-Up Mushrooms becoming invisible Rotten Mushrooms. Several elements, such as Lakitu, do not work at all, while others such as Vines, Fire Bro, and Ant Troopers cause the game to crash.

Clip Through Semi Solids with Vine
The player can clip through semi solid blocks when one collects a Super Mushroom while clinging on a Vine.

Enemy Behavior on Slope
Bowser may move very fast when on a slope, and it may even break stacks of enemies. This can also work with Big Thwomps. Bowser will only work with Steep Slopes in the New Super Mario Bros. U style and the Big Thwomp will only work with Gentle Slopes in the Super Mario 3D World style.

Floating Background Tiles
The player must multigrab and copy the background tile and a ? Block below, and placing the two ? Block under the background tile and then erase it, placing a third ? Block will remove the background tile. This glitch works on any game style except the Super Mario 3D World style.

Fast Koopa Troopa
If the player stomps on a Koopa Troopa and drops the shell at the right timing as it wakes, the Koopa Troopa will go faster than its normal speed.

Item Clipping through Hard Blocks
The player needs to make a stack of at least three Hard Blocks with wings and place a Cloud Block three tiles away from the stack and at most one tile from the top block in the stack. The player then needs to place either a P Switch, POW Block, or Trampoline on the Cloud Block, then place a solid object on the immediate left of the item. The Hard Blocks will fly to the item and it will clip inside the blocks. If the player can collect the item, they can fall and collect it through the blocks.

Move After Goal
It is possible for the player to still have control of their character after touching the Goal Pole. This can be achieved by collecting a powerup that triggers a form change, then by entering the door that leads to anywhere in the Goal Pole. The player will still have control of their character for about 20 seconds, after which the course will exit.

Muncher Super Speed Glitch
Putting a big winged Muncher in a sideways pipe and putting a wall one tile away from the Muncher so it can still spawn and move, then putting a wall over the pipe, standing on the Muncher and being invincible or with a power-up can launch the player very fast as the Muncher is moving fast and the player's speed is stored until he touches the ground. This can be used to cross large gaps.

ON/OFF Clip
If the player Ground Pounds an ON/OFF Switch on the edge of a screen and a Dotted-Line Block is above it, they will clip underneath.

Piranha Creeper Momentum Gain
When the player slides down a Piranha Creeper, he or she can gain a huge amount of momentum after sliding down one.

Power-Up Clip
By placing a downward pipe and a power-up inside the pipe and two One-Way Walls facing each other vertically at least two tiles (due to the Big Mushroom from the Super Mario Bros. style) below the pipe, making sure the player has walls around the pipe so the player cannot collect the power-up from the side, the player can collect the power-up without crouching when small or while crouching when big. This does not work if the player crouches while small or without crouching while big.

Semisolid Platform Clip
If the player places a Thwomp with Donut Blocks and drops them underneath with a Semisolid Platform nearby, the player will clip underneath the Semisolid Platform.

Simultaneous Key Door Sounds
As of version 3.0.0, the sound effects for unlocking and entering a Key Door in the Super Mario Bros. style incorrectly play at the same time when the player unlocks one, making it sound like no sound is being produced when a player enters the Key Door. This only occurs in single-player mode.

Note that prior to version 3.0.0, the sound effects play in the intended order, with the unlock sound playing first before the door opening sound. This does not happen with the other styles.

Sticking on Ceiling
If the player collects a Cape Feather, runs on a Conveyor Belt, and bounces off the Note Block and hitting a Bumper, the player will stick on the ceiling while flying and gliding with the cape.

Super Jump
If a player is in their cape form, flying, descending down on a Bumper and spinning their cape on the exact frame they touch the Bumper rapidly sends them flying upwards.

Teleportation
If the player sets up a Track with a track that they can use a ON/OFF Switch and lures the Enemy or Gizmo onto the ground where the Track is, they will be teleported to another Track.

Wrong Ninji Ghosts
It is possible to make a Ninji Speedruns course load the wrong Ninji ghosts from another course, making them appear to go through walls and do actions that are not intended for the current course the player is on. To perform this glitch, the player must start a Ninji Speedruns course with Ninji ghosts enabled, then turning ghosts off and loading another course. Once another course has loaded, the player must then turn on Ninji ghosts again, close and reopen the menu, and then press Start Over.

Patched glitches
NOTE: As of these patches, performing these glitches is impossible.

Chain Chomp Glide
If the player places a Chain Chomp in a one long gap area and make it turn around to bounce on a Note Block close to the ceiling, the Chain Chomp will fall very slowly as it moves until it stops moving infront a wall. This also works on Munchers using a Buzzy Shell and Trampoline, however; they only move on ground rather than falling very slowly.

Coin in Pipe Limit Bypass (version 1.0.1 only)
When the player goes beyond the Coin in Pipe limit, they cannot place any more of them. However, this can be bypassed by copying a Coin in Pipe until the real limit has been met. Performing this act can corrupt the level making it impossible to save, save as, or upload the course and it will be deleted. This was fixed in version 1.2.0.

Flying Yoshi (version 1.0.1 only)
If the player sets a Yoshi on One-Way Wall facing down and bouncing on a Note Block, and when the lava rises to making contact with Yoshi, he will be launched up in the air very high and descend slowly back down to Lava. When this glitch is in effect, the player cannot ride Yoshi anymore due to the game thinking the Yoshi is in Lava. This was fixed in version 1.2.0.

Flying Thwomp
If the player places a Thwomp facing left and a Buzzy Shell next to it and when it bounces off a Note Block, they will go up into the air and off-screen. They also get stuck in a freezing position if there is a Muncher near on top of Thwomp within the same setup. The player can fix the Thwomp by hitting it with a Buzzy Shell to revert the effects.

Giant Player up on a wall
When the player grabs a Big Mushroom in the Super Mario Bros. style and enters the door with the Dry Bones Shell at the very right side of one vertical gap, the player will go up in the air by holding.

Hidden Air Block
To perform this glitch, the player needs to place a Hidden Block on top of a Warp Door and place a Vine inside, then hit the block to reveal the vine and quickly go inside the door. Then, the player should be able to stand on top of the Hidden Block.

Luigi Flies Up
As Cat Luigi (it only works when playing as Luigi), there is a visual glitch when he bonks into a wall with ground about it. It causes Luigi to fly up but does not affect his real position.

Time Freeze
When the player collects a power up and then goes through a door and gets damaged at the right time, all power ups, enemies, and the timer will freeze in place. The player is also invincible by passing through enemies and cannot die in a pit, poison or lava; however, the player cannot complete the level when the glitch is in effect, making it impossible to upload a course.
