While Monaka delivers a package to Bulma, Goten and Trunks sneak into his delivery truck and are accidentally taken to planet Potofu. A group of space bandits, headed by a teal humanoid Grill attempt to steal a key to an item called the Superhuman Water from an elder named Potaji. The bandits succeed and get absorbed and cloned by the purple viscous liquid. On Bulma's request, Vegeta and Jaco arrive on the planet to search for the children. Shortly after they arrive, the liquid absorbs and clones Vegeta.
