Bruce Mangosteen is a Food Boy that made a minor appearance in the Adventure Time episode "Walnuts & Rain."
He appeared standing next to many other Food Boys, and he also appeared in Finn's vision where he slipped on a flying plate that slid under his feet and glided into a pile of cutlery.
Bruce Mangosteen is just like the other Food Boys. However, his torso is covered with a plump, black mangosteen.
Bruce Mangosteen had no dialogue in the episode. However, he is one of the Food Boys and is loyal to King Huge.
- Finn mentions his name as Bruce Mangosteen during his escape fantasy.
