Flopsy is a self described "cute little bunny." He plays football for Coach Gruesome in Statler & 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. Coach Gruesome keeps sending him back into the game, despite his injuries (including a broken "lucky" foot).
After thinking that Flopsy isn't qualified for this sport, Coach Gruesome decides to cut him off the team. Hearing the news, Flopsy snaps and tackles his own coach. Then, before getting back into the game, he thanks the coach for having him feel pumped up now.
