When the three Para Para brothers fail to find the Dragon Ball on Trunks’ ship, they realize that one of the other three must be carrying it on them. Goku figures out how to defeat the giant worm monsters, and the three make short work of them. The Para Para brothers then command them to hand over the four-star ball, but Goku refuses. The brothers then take off their armor, which turn into stereos, and they start dancing. The mystical beat forces Goku, Trunks, and Pan to dance along with them, and the brothers’ leader takes advantage of their essential paralysis and begins to beat them up. More giant worm monsters appear and crush the brothers’ stereos, freeing Goku, Trunks, and Pan. The three then easily defeat the Para Para brothers. Later, when searching the brothers’ ship for the stolen Dragon Ball, Pan and Giru accidentally trigger the launch sequence, and the ship takes off, leaving Trunks and Goku behind.
