List of Super Mario Galaxy 2 glitches
This is a list of glitches in Super Mario Galaxy 2. Unless otherwise noted, all names are unofficial.
Audio
Ice music on fiery planet
On the starting planet in Shiverburn Galaxy, in cloud form, the player must hit the switch that freezes the planet and return to where they started. They should then Long Jump towards the Magma Slice Planet. Then, they should make a cloud and Long Jump, repeating two more times. They will be pulled by the planet's gravity and land on it, though the starting planet music will still be playing.[1]
Squizzard battle loud sound glitch
During the Squizzard battle, if the player defeats him and is hit simultaneously, a loud sound will play. When the cutscene finishes, they will take damage and be knocked back.
Graphics
Chance Cube room wall glitch
If the player visits the Chance Cube room and faces towards the screen while talking to a Lumalee, the wall is unfinished, showing the sky.[2]
Cloud clipping
In Cloud form, if the player creates a cloud as they get a Power Star while approaching from the side or top, the camera will clip through the cloud, while part of their character will be inside it.[2]
Credit graphics glitch
During the credits, when the player is on the teeter-totter moon, if the player Ground Pounds the left side of moon and performs a backward somersault while it rises, they will fall off the moon, followed by a Bubble surrounding them. They will be stuck in the bubble falling endlessly for several credit scenes as it attempts to return the player onto the moon, with the planets visited off-screen. Eventually, they will reach solid ground, but the graphics will broken in various ways. For example, the platform in the Yoshi Star Galaxy may become invisible; the scene with the defeated Bowser may only consist of a desert background, and the camera may point the wrong direction.[2]
Disappearing characters in first-person
If the player stands close to certain characters and enters first-person view, the character will disappear, with only its shadow present. This is most notable with Supermassive Galaxy's Giant Lumas and Cosmic Cove Galaxy's penguins.[2]
Disappearing Piranha Plant
To perform this glitch, the player should go to Supermassive Galaxy. They should trigger the Checkpoint Flag and die. When the player respawns, they should wall-jump up the gap between the Thwomps, face the camera, then Long Jump off the edge of the one on the right, allowing them to return to the start. After, the player should progress through the level normally. When they reach the second Piranha Plant, the plant can be spun to release water and damage the player, but cannot be seen. Shortly after, dirt will spawn continuously, lagging the game.[2][3]
Disappearing platforms
Near the end of Sneaking Down the Creepy Corridor, if the player falls between the moving platforms, the camera will clip through the platforms, while they disappear.
Floating hair glitch
If the player enters first-person view during the credits, the character's hair can be seen, remaining stationary even if the player rotates the camera.[2]
Floating Toad glitch
At the yellow Starshroom in Mini-Planet Daredevil Run, if the player stands on the side window where the Toad's back is visible and enters first-person view, the Toad will be floating in midair.[2]
Frozen Piranha Plants
At the end of Search for the Toad Brigade Captain, if the player looks back, Piranha Plants can be seen, but they are frozen, despite their surroundings remaining animated.
Frozen meteors
On the Ice Magma Skate Planet, if the player enters first-person view and look directly at the meteors, the meteors will be frozen until the player exits first-person view or looks away.[2]
Low-resolution planet glitch
On the Lava Chomp Planet in Where the Chomps Are Made of Gold, if the player turns their character to face them and then Long Jumps to fall off the planet, right before they fall off, the planet will be low-resolution, as if the player was far away from it.[2]
Persistent starlight glitch
In Twin Falls Hideaway, if the player releases the Power Star from the crystal, then jumps down and enters first-person view, the starlight will still be located on the star's original location.
Post-death falling glitch
If the player lands on lava with one wedge of health while jumping and falls into an abyss, their character will not be silhouetted as they normally would.
Reach the Starshrooms
At the split in Rolling Coaster Galaxy, if the player jumps towards the blue Starshroom, they can fall through the Starshroom and out of bounds, as the Starshroom has no gravity. The player can also reach the green Starshroom if they stand on the fence at the beginning and Long Jump towards the Starshroom, though this one has gravity. [4]
Rosalina angle glitch
Normally, on Starship Mario, as Mario is shorter than Rosalina, if he talks to her, she will look downwards while talking to him. However, as Cloud Mario, if he spins a cloud while standing next to her, crouches, and talks to her, despite being above her, she will still look downwards. This can also be performed with the Mailtoad or Banktoad, though they will instead be invisible.
Smeech with Star
If the player collects a Power Star with a Smeech on Yoshi, their character and Yoshi will perform the same animation, but the Smeech will remain stuck to Yoshi.[2][5][6]
Squizzard's floating ball glitch
Occasionally, during the Squizzard battle, if the player Long Jumps left or right when a fireball hits Squizzard when his mouth closed and is about to toss a spike ball, the ball will float in front of his hands briefly.
Void glitch
On the pier in Melty Monster Galaxy, if the player enters the Warp Pipe leading to The Chimp's Bowling Challenge and returns, part of the background for the challenge can be seen.[2][7]
Yoshi's long tongue glitch
On Starship Mario, while riding Yoshi, if the player steps near a Warp Pad to the Starshroom and presses 
quickly, Yoshi's tongue will be stuck on the Warp Pad until the player presses again or jumps off him.[2][8][9] This can also occur when entering or exiting the engine room, where his tongue will briefly be long.[2] This was fixed in the Nintendo Switch re-release of Super Mario Galaxy 2.
Yoshi's puffed cheeks glitch
In Yoshi Star Galaxy, if the player activates the Launch Star right as Yoshi eats the golden fruit, Yoshi's cheeks will remain puffed until the player lands. [2]
Yoshi's quick legs glitch
On Starship Mario, if the player runs towards the fence, Yoshi's legs will move rapidly.
Physics
NOTE: These glitches result from how Mario and/or other characters and objects interact with the world.
Bee in wall glitch
In the area in Honeyhop Galaxy where falling bubbles first appear, in bee form, the player must start from the top of the left wall and then jump off, pressing 
in short rounds to fly to the Bee Mushroom, which clips them through the wall. Alternatively, the player can jump left off the platform to the right of a nearby Choppah, then fly towards the screen and back to the wall.
Depending on the method, they may be pulled out of the wall or remain stuck. If the player is stuck, they may be able to exit by spinning, though if a Ground Pound or Homing Attack is performed, they will likely remain stuck until the level is restarted. They may also be pushed upward through the wall while inside, being unable to do anything but spin.
Behind Goomba statue glitch
On the White Out Planet, if the player Ground Pounds the back of the Goomba statue near the Li'l Brr, their character will slide behind the statue, followed by vibrating rapidly. The player is trapped and must exit the level to escape.[2][9]
Boo in wall glitch
In the Howling Tower, in Boo form, if the player turns themselves transparent, enters a wall, and remains inside until they become opaque again, they will remain inside the wall.
Bugaboom's Planet gravity glitch
On Bugaboom's Planet, if the player uses the clouds from the Cloud Flower to Long Jump back to the previous planet, there will be no gravity.
Red-Blue Panel jump glitch
If the player runs towards the empty space a Red-Blue Panel flips to when spinning, spins before reaching the space, falls onto the panel as it rises, and Long Jumps before the panel stops, their character will be launched high in the air.[2][10] This can also happen in cloud form if they jump immediately after forming a cloud.[2]
Fly around Cyclone Stone
Near the first Green Star in Stone Cyclone Galaxy, if the player waits for the Tox Box to pass, backflips at the right time, lands on the Tox Box when it is flat, then jumps as it begins to turn, they will be launched into the air and circle the planet several times.[11]
Far flying glitch
In Return of the Whomp King, on the Whomp King, if the player jumps as he stands back up, he fling the player far away from the battlefield, causing them to lose a life. This also occurs with regular Whomps.[12] This glitch was discovered when a fan jumped at the wrong time when performing the midair crush glitch.
High backflip glitch
On the Whomp King's head, if player performs a backwards somersault as he is about to fall, the player should end up doing a very high backflip. This also occurs with a Thwomp moving upward.
Inside Digga-Leg Planet
Occasionally, when using the Spin Drill on Digga-Leg Planet, the player can clip through the planet. The cause is unknown.
Invisible platform glitch
Near the small fence in Throwback Galaxy, if the player jumps at the right time, they will land on a small platform with nearly no room, virtually standing in midair. If the player runs towards the main planet, they will clip through the fence and be back on the planet.[2]
Long Jumping off water
While in water, if the player presses 
and then with a shake of the Wii Remote between presses, they will be able to perform a Long Jump in water.[2][13]
Skeeter clip in Throwback Galaxy
In the Throwback Galaxy, if a falling bridge block falls on top of a Skeeter, it will clip through the bottom of the fortress below the black hole.
Stuck Crabber glitch
In Surf, Sand, and Silver Stars, if the player spins a Crabber into deep water, the Crabber will dig back to the surface, but only half of it will appear. It is frozen, and the player cannot interact with it. After a couple of seconds, the Crabber will come back up, though a couple seconds after, it will be standing in midair. When it spots the player, it will fall back to the ground.[2][14]
Off the edge glitch
On Starship Mario, on the wall with the entrance to the engine room, Luigi must crouch down, walk at the edge, stand up, and slide. He will then be off the platform's edge, unable to spin or ground pound, along with his model frozen.
Out of bounds gravity glitch
In the area with gravity chambers in Sailing the Sandy Seas, the player should wall jump to the platform, fall down, and enter the green pipe. When they exit, they should go right, fall, enter, and then exit the spinning cube's gravity without touching it. Then, the player must enter the pipe again. When they exit, they will fall through all walls and out of bounds, falling for approximately thirty seconds before losing a life.[15]
Tower clipping
On top of the tower with the Whomp in Throwback Galaxy, if the player stands at the edge where the Whomp will land and jumps before being crushed, the player will be pushed to the other side of the planet with the Whomp King.[2][16]
Lava skating
In Prince Pikante's Peppery Mood, if the player skates on lava while invincible, they will skate through it for a short period of time.
Wood skating
In Twin Falls Hideaway, if the player freezes the lake and goes to the small wooden platform closest to the waterfall, there will be a small space where the player can skate. The player can go back and forth and jump, but they cannot turn around.[2]
Sliding between platforms
At the start of Chompworks Galaxy, if the player stands on the column in the bottom-right corner of the ramp and walks towards the ramp, their character will continuously slide between the two platforms.[9][17]
Stuck in nose glitch
If the player walks on Starship Mario's nose a certain way, then lands on the ground next to it, they will be stuck in between the nose and ground, though they can escape by jumping.[2]
Superspeed jump
In Fluffy Bluff Galaxy, one of the hills on the Starting Planet has a section that gives the player a very large amount of speed if they walk on it. It is possible to jump all the way to the final planet of the galaxy this way.[18]
Upside-down Yoshi glitch
On Starship Mario, if the player dismounts Yoshi in the door to the engine room and pushes him into it, he will flip upside-down and in midair.[19]. This also occurs if they dismount Yoshi as their character enters the door.[9]
Wrong gravity glitch
In Rightside Down Galaxy, the player can skip the first switch by Long Jumping to the upside-down question block, then Long Jump onto the Banandelion on the ceiling. They will slide up the Banandelion and land on the ceiling, despite gravity being pointed downwards. Walking too far to the right will correct the gravity.
It is also possible to walk on the wall at a red region in Upside Dizzy Galaxy, though the method to perform this glitch is unknown.
Yoshi jump glitch
Near the end of the Giant Ramp Planet, if the player jumps right before reaching the edge of the Launch Star's platform, Yoshi will jump very high as if he was Dash Yoshi. When performed with a Dash Pepper, the player can reach Penguru without needing another Dash Pepper. This can also be performed with the second Dash Pepper, though they will end up much higher, and if the player continues holding forward on the 
, they will fall and lose a life.
Yoshi stuck in tree glitch
On Starship Mario, there is a tree on the left side of the deck door to Luigi. On the upper part of the deck, if the player Flutter Jumps to the top of the tree, Yoshi will get stuck in the tree, though he will return to normal when he returns to his egg.[2][20] If perform slightly differently, his eyes will be closed when performing a Flutter Jump, but will remain idle. If he returns to his egg or the player jumps on him, his eyes will be open again.
Yoshi underground
In a large body of water in Starshine Beach Galaxy, if the player goes to the shallow part where he can still stand and jumps off Yoshi, when he returns to his egg, he will briefly go underground before rising to the surface. A similar glitch also occurs if the player slowly walks to deep water with Yoshi, where the player falls into the ground temporarily, due to the game attempting to bring the player fully underwater too early.
Yoshi underwater glitch
In Starshine Beach Galaxy, if the player dismounts Yoshi near a body of water and pushes him into it before mounting him again, he will be able to walk underwater, even after leaving the water and re-entering it, though if the player falls off an edge, the glitch ends.[2]
Zero-gravity Whomp King
In Return of the Whomp King, If player leads the Whomp King to the edge of the platform until his feet are almost off the edge and then hangs off the edge between his feet, when he slams down, he will land in midair, though he will still make the sound of slamming the ground. Despite being in midair, he will not fall down, unlike normal enemies.[2]
Scripting
NOTE: These glitches abuse interactions that cause objects or displayed information to perform unintended behaviors.
Coin resurrection
If the player takes damage and has their health reach 0 but they land on top of a coin, their health will increase to one and they will not die.
Cosmic Clone camera glitch
At the start of Silver Stars Down Deep, if the player jumps to the Crystal and Spins it right as the Cosmic Clones appear, when the camera attempts to show the clones, it will instead turn to the other side of the planet. Due to the player's character being frozen and most controls being disabled at this time, the player is unable to do anything, forcing them to restart the game.
Cosmic Clone spawn glitch
On the Cosmic Platforms Planet in The Shadow Lining, if the player gets close to a Star Chip and grabs it, they will get the chip, but the Cosmic Clones will not appear.[2]
Credits freeze
During the credits, if the player continuously mounts and dismounts Yoshi, the screen will briefly freeze.
Delayed transformation glitch
In the area with Trapdragons and Spindleburrs in Bumble Beginnings, if the player is hit by a Spindleburr while in bee form in midair, they will fall onto a Bee Mushroom. When touching the Mushroom, the transformation sound will play, but they will not transform until they recover. This can also be performed with the Cloud Flower in Shiverburn Galaxy by falling in lava and touching the power-up.
Disabled electric rail
On the Banzai Bill Planet, if the player touches an electric rail after losing two wedges of health, they will pass through it without being hurt.
Falling onto Starship Mario with Yoshi
To perform this glitch, the player needs to use Yoshi and get on the Warp Pad that takes them to the red Starshroom. Then, the player should backflip and use the "Infinite Fluttering" glitch. If the camera is turned, the player should let go of the button. The player must wait until they land on Starship Mario.
Fearsome Fleet teleportation glitch
In Bowser Jr.'s Fearsome Fleet, the player should activate the second moving platform and wait for another moving platform on the first track to appear. When it appears, the player should jump on it and walk into the nearby stationary platform's wall. When the platform disappears, they will be teleported back to the start.[2]
Infinite Fluttering
To perform this glitch, the player should Flutter Jump. When Yoshi is almost finished, the player should release and press , then release and hold , repeating this to continuously gain height.[2][21] This was discovered shortly after the game's release. This glitch is known by many as "Infinite Fluttering", and has become the most well-known glitch in the game.
Circle around the Castle Planet
On the top-right corner of the Platform Planet, if the player Flutter Jumps until they leave the planet's gravity, they will be pulled towards the Lava Castle Planet, where they will infinitely circle it until they exit the level. They can also jump off Yoshi, but will not be able to get back to him.[2][22]
Complete Grandmaster Galaxy with Yoshi
On the top-right corner of the Flipswitch Panel Planet, the player should Flutter Jump. The screen will turn white, and after a while, they will enter the Electric Maze Area. The player should keep fluttering until they reach the Launch Star, allowing them to complete the level. It is also possible to complete the Electric Maze Area by Flutter Jumping inside the fence.[23]
Drop glitch
At the end of Saddle Up with Yoshi, the player should Flutter Jump upward for about one minute, then go on the invisible platform, and walk left. This results in the player falling, with many possible outcomes, such as repeatedly jumping, floating, teleporting, or falling down to nowhere. Touching the Coconut freezes the game.[2]
Dying in credits
When showing Peach's Castle during the credits, on top of the cake, if the player Flutter Jumps until the screen pans upward, the player will go out of bounds, with "Too bad!" (or "Game Over" if the player has no extra lives) appearing, followed by the screen turning black and the music stopping. This does not stop the credits, as the sound of pages turning is still played. At the end, "The End" will appear, with "Too bad!" overlaid. Afterwards, the game will return to normal.[24][2]
This can also occur in Tall Trunk Galaxy if the player has 120 Power Stars. When shown, the player should grab the Bee Mushroom and wait until Freezy Flake Galaxy appears. Then, the player should fly towards the screen while they are still in midair. If performed correctly, they will go out of bounds, with "Too bad!" being displayed.[25][2] However, if the player dies as soon as the page is turning during the credits, the game will crash.
Falling off Starship Mario
On Starship Mario, if the player Flutter Jumps for a long time, they will go out of bounds and lose a life.[26] This can also occur with Cloud Luigi on the Starshroom, if the player backflips, creates a cloud, Long Jumps away from Starship Mario, creates another cloud, backflips, creates the final cloud, and Long Jumps away again.[citation needed]
Flutter to the Chance Cube room
On the lower-right side of the deck on Starship Mario, the player can reach the Chance Cube room if they Flutter Jump in that direction for a long time. The player can enter the room, but the Starship Mario music will still play.
Invisible wall glitch
In Bowser Jr.'s Fearsome Fleet, if the player Flutter Jumps to the Megahammer Planet, when walking around the planet, they will hit an invisible wall.
Long fall glitch
On the far-right corner of Flipswitch Panel Planet, the player must Flutter Jump towards the abyss until the screen turns white. Then, they should jump off Yoshi and Ground Pound. Their character will shrink, and the background will return to normal. They will fall for a long time before losing a life.
