As you play WarioWare, you'll unlock a few extra minigames to play.
Dr. Wario
Everybody's favorite Nintendo puzzler, this time featuring Wario. Outside of some minor aesthetic differences, this is just about a 100% accurate version of the original Dr. Mario (except there is only one music track). You can unlock this by scoring more than 20 points on Jimmy's first set of games.
Jump Forever
A jump-rope game. You can unlock this by completing Jimmy's first set of games.
VS Chiritorie

VS Chicken Race
Complete Mona's games to unlock this versus game. The objective is to launch your skateboarder as far as possible without propelling them off the edge. Score is best 2 out of 3.
VS Dong Dong
