Chomper Stomper is a quest in Mario Party Advance that starts when Chain Chomp is visited. When he is visited, he excitedly asks the player if they want to duel him: declining leaves him disappointed, and accepting makes him excited and starts the quest. He explains that if the player beats him at the Duel minigame, Chain Saw, they are allowed to keep it for themselves. Once Chain Chomp is defeated, he relents and rewards the player with the minigame.
