Apple Kid also tells Ness that he is sending the Yogurt Dispenser to him via Escargo Express's Neglected Class.

Soon afterwards, an Escargo Express employee arrives and tells Ness that he lost his package in the middle of the Dusty Dunes Desert. Ness and Jeff must then journey through Monkey Cave. When they reach the end of the cave, Talah Rama gives them the Yogurt Dispenser.

When Ness and Jeff return to Fourside, they find Pokey's maid, Electra, standing around outside of the Monotoli Building.
