List of Mario & Luigi: Bowser's Inside Story glitches

This is a list of glitches in the game Mario & Luigi: Bowser's Inside Story.

After exiting the Pump Works for the first time if Mario or Luigi reenter the Pump Works hit a save block before fighting the Scutlet, the message that usualy appears the middle of the screen when hitting a save block will say that Bowser has the abillity to breath fire again even though the Flame Pipe will still be blocked.

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.

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.

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.

When the player defeats a Pep that's 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 a Pep sound playing over and over again.

The game wasn't designed for 10,000 or more damage to be dealt to an enemy. If the player does this, as soon as the damage is dealt, the game will crash. The player must reset the game but however, after doing the glitch, it may bring corruption signs, such as lagging, glitching, and freezing or crashing. The game will be even more corrupted the more times the glitch is performed until it gets unplayable. In some PAL releases the glitch should have been fixed, but it can still be accomplished normally.
