Petey Piranha is certainly recognizable as a Piranha Plant, but he differs starkly from a typical one. According to Mario Superstar Baseball, he got his looks from a mutation. Petey is characterized by a remarkably large head and a comparably small body. He has a round, protuberant belly and a large belly button, but it's only visible if his stomach is inflated with a great quantity of water. Additionally, he has leaf-like arms and stubby legs, both of which grant him mobility beyond his pipe-dwelling "cousins". He also has green lips, which are similar to the lips of the old Piranha Plants but now contrast the white lips of the new Piranha Plants. He wears red pants with white polka dots, matching the coloration of his head. His most distinguishing feature is a ring of yellow petals with orange rims around his head, resembling a crown or a mane. In his first appearance, these petals have an iridescent quality, becoming a vibrant, fiery orange or a shiny white (with pinkish rims) depending on the angle of the light, but this trait is no longer present beyond Super Mario Sunshine. Petey is also of a much greater size than normal Piranha Plants, easily standing six times Mario's height, though when depicted with a sprite or encountered in sports and spin-offs, he's smaller. Mario Superstar Baseball is the first game to portray Petey Piranha with a tongue, which was also seen in every game following.
