Special Delivery

Special Delivery is the twentieth episode of Ben 10: Omniverse.

Plot
Mr. Baumann becomes fed up with Ben after having destroyed his car yet again, so he forces Ben to deliver a few packages for him to make up for the damages. During the delivery, though, Corvo accidentally takes a bag belonging to Ben containing goldfish that is identical to his own, which contained a rare dwarf star that was to be auctioned off for a great amount of tayden. Psyphon unintentionally gives everyone who attended the auction the opportunity to find Ben and get the dwarf star, but he doesn't do so without a fight.
