WarioWare: Touched
Nasty Garlic: When selecting a character's microgames, drag some Nasty Garlic to Wario and have him change to Wario-Man so you can play his games. Found by Paperlemmy.
Tennis Ball: On the opening screen (the one that says touch to start) there is a tennis ball that you can throw around. If it's not there at first, then it will come in a while. Found by Hyper Mario.
Wario-Bomb: This turns Super Wario back into normal Wario. Found by M&LSuperstars.
