The players must use their hammers to smash the pegs impeding their ball's progress and allow it to the bottom of the pinball machine-like area to win the minigame. The three players have a much bigger, blue ball, but more people, while the solo player has a much smaller orange ball.
Intro- The view changes from the bottom of the area to the top. The players then emerge from the sides of the screen, and the minigame begins as the balls roll into the arena from Warp Pipes.
Ending- The victor's ball rolls down the pipe at the bottom of the area. The winner(s) then perform their victory animation in the center of the area.
