Chain-Chomp Challenge is Wario Factory's minigame in Mario Power Tennis. Four players must feed Chain Chomps with tennis balls to score points. At the beginning of the match, the players' positions are shuffled twice. Normal Chain Chomps give players one point per ball it consumes. Bob-ombs cause the Chain Chomp to be enraged, but makes the player gain 2 points per tennis ball. If the red Chain Chomp is hit by another Bob-omb, however, it chases the player. The player must press or shake the Wii remote in the Wii version to reach the water nozzle, resembling F.L.U.D.D., to calm it with a spray of water or loses points if Chain Chomp hits the player. Water balls also appear, which calm angry red chain Chomps, but if a water ball hits a normal black Chain Chomp, it sleeps and does not eat tennis balls. A sleeping Chain Chomp can be woken with a Bob-omb. It is also possible to hit objects into other player's Chain Chomps, affecting their progress. When time runs out, the player with the most points is the winner.
