Goombario is a Goomba and a big fan of Mario, with whom he joins forces. Goombario lives to the west of Toad Town along with his family and a single Toad in Goomba Village. The Goombas of his family break the stereotypical reputation of Goombas by being peaceful, intelligent, and friendly to Mario. Goombario himself wears a blue baseball cap, which, aside from his smile, is the only physical indication that he is not a typical Goomba.
