"Blaaaargh!"
— Petey Piranha
Petey is a minor character in the Bowser's Kingdom show, where he is voiced by Steve Button who also voices Steve The Piranha Plant due to the both of them being cousins.
Petey Piranha at the Villains' Olympics
First appearing in Episode 7, Petey is Steve's cousin and together they form Team Piranha Plant and compete in the Villains' Olympics. Petey is constantly vomiting and when Team Piranha Plant place third in the competition, they apparently win a life time's supply of milk. Steve points out that Petey is actually lactose intolerant, as Petey can be heard vomiting in the background.
In the Bowser's Kingdom movie, Petey finds Hal (disguised as Luigi) and Princess Toadstool/Peach hiding in a Ghost House and vomits on them. As Hal asks Petey what the hell is wrong with him, Petey orders the rest of Bowser's minions to charge at them. Jeff and the Karate Duo Number 1 suddenly break through a wall and send their car flying into Petey's open mouth, knocking him out.
