Cutie Battle Contest, Semifinals
From the Super Mario Wiki
Wendy's cutie battle contest starts the semifinals, and Captain Goomba and Captain Boo continue to use Captain Shy Guy as their cuteness factor. They battle Elite Pestnuts, Boomerang Bros, Koopa Paratroopas, Starkisses, Green Magikoopas, and Wendy herself. After they unbrainwash Wendy, both teams forfeit the contest, causing the announcer to declare the Star Angels as the winners instead. Wendy then joins the Goomba Squad.
