Punch Up is a minigame in World 3 of Dance Dance Revolution: Mario Mix. The player has to tap left, up, or right on the Dance Pad to have Mario or Luigi knock out as many Koopa Troopas as they can by using the controls of the punching machine. Knocking out multiple Koopa Troopas can earn them more points. If Mario or Luigi hit a Toad, they will not be able to move for a short time.
Those pesky Koopa Troopas are back. Use your machine to punch them out of the way!
