As a joke on the baby Mario characters, I propose Teenage Wario. The goal of the game is to get expelled from High School. But the problem is, everyone in High School loves you somehow, even the teachers. Wario must think of creative ways to try to get expelled. Maybe at the end of the game, it won't be an educational game per se but so that it's not too dark, Teenage Mario instructs him to stay in High School and he listens.
