The gang's house has disappeared. They attempt to recover it using Bad Bob's "Go-Back-In-Time-O-Tron".

The gang journey to the North Pole, and drill a hole to find out what's at the centre of the Earth.

Bob discovers he has a genius for curing hiccups and the gang temporarily become very rich.

Rex and his friends are in the process of fixing up the patio behind the house. But a group of ants who live in the backyard are not about to go without a fight.

Bob's eating is growing out of control. Rex suggests that Bob needs to watch what he eats and exercise, but Bob has a better plan: plastic surgery courtesy of Dr Dog.

Rex goes to Dr Dog, and returns home missing an ear. The gang returns to Dr Dog's to investigate, and find that the physician has now begun to shift his focus to genetic engineering.
