The team of three stands on a large Bob-omb painting while 16 "?" tiles cover it. Meanwhile, the camera pans out to reveal the rest of the arena (with Bob-ombs in the stands) and the solo player, who is in a robot with two mechanical arms. The minigame then begins.
The goal of the team of three is to dissolve the tiles by ground-pounding them. On the other hand, the solo player's goal is to knock away the other three players by using a robot with two large mechanical arms wearing boxing gloves. The single player has to speak into the Mic to command the machine to rotate, double-punch, rocket-punch, punch left, or punch right. If there is no Mic, the commands are selected from a blue box. If the robot's gloves or arms hit a team player, that player is eliminated. The solo player wins if they eliminate the other three players. The team players win if they ground-pound all the tiles.
If the solo player wins, they and the robot perform victory poses. If the team players win, they stand on the now-revealed painting, performing their victory poses while Bob-ombs drop in on the solo player's robot and destroy it, after which various parts of it catch on fire due to electrical failures.
