This is a list of glitches in Mario & Luigi: Bowser's Inside Story. For glitches exclusively found in the remake, see List of Mario & Luigi: Bowser's Inside Story + Bowser Jr.'s Journey glitches. Unless otherwise noted, all names are conjectural.


Balloon Mario tutorial skip

After speaking with Dr. Toadley, the player will see a cutscene if they return to the previous area. If the player positions himself on the left side of the entrance to Toadley Clinic, then press down and then again press three times to the left, it can cause using Spin Jump to make Mario and Luigi go on top of the entrance. The brothers can then use Spin Jump to move to the right and catch Birdley without learning the Balloon Mario technique.[1]

Bowser punch glitch

The player must be Mario and Luigi inside of Bowser's Body. After saving, quitting, and re-opening the game, the player must press Y Button. Instead of breathing fire, Bowser will do a punch.

Bowser X corrupted graphics glitch

This glitch is exclusive to the European version, due to bad code port. While fighting Bowser X, There is a chance that the entire screen will be filled with corrupted graphics. For now, there are two known ways for this to be activated: The first is for Bowser X to become giant on turn 21. The second is by using the medal that heals the brothers' life. Corrupted graphics are everywhere and can make using a special attack much more difficult. The glitch ends when the battle is won or lost.[2]

Confused action icons glitch

When the player begins the Mushroom Ball challenge in Toad Town and has the ability to tunnel underground, sometimes popping back out will cause the action icons to be in a glitched state after getting the Mushroom Ball out of the ground. This will move the action icons further up and make the game think they have or have not been switched and also frozen in place.

The action icons will also disappear if the player opens and closes the star menu, though they still function correctly. The player can fix this by simply entering any area.[3]

Frozen battle glitch

If the player is battling Bowser X, and when he is doing the attack where he grows giant, and one of the bros is hit by the fire, then they will fall behind, and sometimes the game will freeze. The music is still playing, although it is playing the same note over and over again.

Luigi wearing Mario's clothes glitch

When the player goes to the blue area of the Flab Zone and jumps into the mucus and through the pipe, Luigi will oddly fall in front of Mario. Luigi will then have half green and half red sleeves and Mario's overalls. When the player jumps as Luigi, he will jump "out" of Mario. When Luigi falls back down, he will look like he fell back "into" Mario.

Save Block lag glitch

Bowser should be facing a save block, close enough to punch it. The player must save while inside Bowser's body. They must then quit the save file. After reloading the game, the player must press X Button or Y Button to make Bowser punch. He will do the slide punch animation, and after a few seconds, will hit the save block.

Stuck statue glitch

When Bowser is pushing a Statue of Fawful in Bowser's Castle, there is a glitch where Bowser will get the statue right to the wall but will be stuck. Mario and Luigi can't do the double jumps on Bowser's legs to make him push, they will only do normal jumps. Bowser's minions won't push the Statue either though, making the Statue stuck. If the player restarts the game then the glitch will be fixed and the game will go on as normal.

Talkative Pep glitch

When the player defeats a Pep in its POW form and tries to attack, a glitch may occur. Mario or Luigi must counterattack by using their hammers right when the Pep makes a sound effect, and if they defeat the Pep, during the rest of the battle, and even in the victory scene, the player can hear the sound clip for the Pep playing over and over again.

Trapped in Pipe Yard glitch

Warning! Performing this action may corrupt your game's save file.

If Bowser is bloated after eating one of the leftovers, once the Flab Zone is active, the player must go to the Pipe Yard, and when they do, a glitch may occur. Mario and Luigi will keep walking, but Luigi will be stuck. The player has to reset the game after this. However, if the player (as Bowser) saves anyway after the glitch is performed, the save file will become softlocked, making the Bros. unable to progress through the Pipe Yard.
