Mario: Makes out with Peach, and attempts to win her over by bringing her with him to his plumbing job.
Luigi: Tries and epically fails to do what Mario does.
Peach: Although she has amazing attacks, she waits around until a large turtle captures her so a fat Italian plumber will rescue her. Eventually Mario will get bored of doing so and will leave Peach in her cage. That way she won't appear in the next game.
Bowser: Captures Peach, stares at her for a while, and then just leaves to go back to his swamp (he is a turtle).
DK
lays the drums in the band of jigglypuff, and that Barbara. (jigglyouff sings).
