This is a strange glitch in Super Mario 64 DS. It makes Mario huge, fat, and running backwards all the time. To perform this glitch, you must have an updated Action Replay.
How to do itEdit
You must have two codes enabled to do this. The Giant Character code, and the Invincible code. Get hurt. Mario will become a different version of Retarted Mario. If you get a star, lose a life, or exit the level, Mario will return back to normal.
