One of the Cheep Chomp mechs opens its mouth. Players 2 and 3 throw one ball in, one after the other, while both Players 1 and 4 throw one ball at the same time. After this scene, the mouth closes.
Players need to throw balls into the mouths of Cheep Chomp mechs to earn points. No points are earned if the ball hits the mech while the mouth is closed, one point is earned if the mouth appears normal, and three points are earned if the mouth is glowing with an arcing rainbow. Whoever scores the most points after 30 seconds wins.
On the Challenge Road, this is the third challenge of Mushroom Beach and the 24th challenge overall. The goal is 35 points for the normal challenge and 40 points for the Master Challenge.
