Flopsy

From Muppet Wiki

Flopsy is a self described "cute little bunny". He plays football for Coach Gruesome in Statler and Waldorf: From the Balcony episode 32. The little bunny is sent into the game to annihilate the other team but continually gets pummeled by the bigger players. His coach keeps sending him back into the game despite his injuries (including a broken "lucky" foot) until he snaps and tackles his own coach.
