List of glitches in Mario & Luigi: Dream Team
This is a list of glitches occurring in the game, Mario & Luigi: Dream Team.
Freezing occurs in the game on certain occasions, but mainly toward the end of the game in Neo-Bowser Castle, where the Mario and Luigi find themselves at idle animations and not being able to do anything. This appears in all original versions of the game, but a patch was released on September 5, 2013 fixing many of these issues.
Antasma X Glitch
Broken Motion Controls Glitch
In some points in the game involving gyroscope controls, it is possible the game stops registering any gyro movement altogether. This can cause the battle to become impossible to win because it is impossible to avoid damage. This is most likely to occur in the Zeekeeper battle with Giant Luigi in Somnom Woods. During the Zeekeeper battle, the game is slow or inaccurate at registering all motion controls, which makes it extremely hard if not impossible to dodge attacks.
Corrupted Save File
It is possible that the game will display a black screen with a message saying that the save data has been corrupted when the player loads it up. This will force them to start over the whole game. Something similar also happens when selecting a new save file, after selecting a file, the screen goes black and freezes, taking the player to the Home Menu. These only happen on the digital version.
Luigi Standing on Lava
The player needs to go to Neo Bowser Castle, in the sections with the moving, fire breathing Bowser statues. If the player uses the Side Drill move in the area where the Bros. Ball is needed and cross the moving statues, Mario will land on the platform, but Luigi will land in the lava and stand there without jumping out.
When visiting Dozing Sands for the first time, the player can skip all of the activity involved in retrieving the Dozites needed to access the area where Torkscrew is fought. In the area where the badge shop is, Mario and Luigi need to lure a Sandoon to the dark gray high ledge in the east, and while touching the wall, both brothers must jump on it to initiate a battle. The player must then flee from the battle, hold and repeatedly press the Buttons. If done correctly, Mario and Luigi will do another jump in the air and over the high ledge. This is a frame perfect trick, so it might take a while. Currently, this sequence break works in all versions of the game. 
No Demo Sign
The player needs to go to the Menu and then press Guide, then press Attacks. The demo sign appears in a little while after they scrolled down then scrolled back up quickly. If done correctly, they will have no demo signs while selecting the attack. When they press the Y button, it can start the demo even though the sign is not here.
Out of Bounds
Standing On Water
The player needs to go to Driftwood Shore and then go to the cave after they talked to Broque Madame at Rose Broquet. They will earn an old lithograph. After they went to the door, they will enter the cave. On a spot, they have to hold the left button on the Circle Pad for 1 minute. After that, they have to hold the right button on the Circle Pad, If done correctly, Mario will stand out of bounds, and if the press the right button on the Circle Pad some more, Mario and Luigi will walk on the water.
