Tom and Jerry in Mouse Attacks! was released by Ubisoft (known for their Prince of Persia games for the PS2) in 2000 for the Game Boy Color. Tom has captured and locked up five of Jerry's friends, and it's up to the little brown mouse to save them.
A series of glitches and tricks are used to quickly obtain all the special items, free Jerry's friends, and defeat each level's boss. The author, Mukki, explains these on the movie's submission page.
