Waluigi needs his own game.

Wah Even though he is not my favourite character, he has so much potential. So here is my idea: Waluigi is fed up with mario and luigi being the heroes and he wants a shot. So he decides that he is going to be the one who saves peach the next time she gets kidnapped. When he reaches bowser's castle, he styles on bowser with his kicking skills and sends him straight into lava.
