Mario Party 4 Cheat Codes

While playing the game push L to hear your character's taunt. You can do this on game boards, but not in mini-games.

If you win all five boards in story mode and collect all presents for one character, Bowser will challenge you on his board. If you beat him and his mini-game, you can now select the Bowser's Gnarly Party in Party Mode by highlighting Koopa and pushing Right.
