Pete: Part 2 (S08E07)

The Dwarfers find themselves in a life-threatening situation when they devolve Pete the Sparrow into a Tyrannosaurus Rex with a time-wand, and he goes on the rampage in the cargo decks. To make matters worse, Pete has eaten the time-wand, so the Dwarfers hatch a cunning plan to get it back via a dinosaur portion of cow vindaloo. (iTunes)
