A certain Bumpty appeared in Tetris Attack, allied with Dr. Freezegood. In here he was depicted as Yoshi's friend, but enchanted by Bowser and his minions to work for him. Yoshi and Bumpty became friends again after freeing him and Dr. Freezegood from the spell. He also notes in the game, that others say that he's cute, but he really doesn't like it, and would like to be said as cool.

 * The Cooligan enemy in New Super Mario Bros. Wii is very similiar to the Bumpty in that they are both Penguin enemies encountered in Ice stages. The Penguin Suit power-up also resembles the Bumpties.
