 Graeme falls through the floor of their office and lands in a cave far below. Tim and Bill follow him down and there they find a Tyrannosaurus Rex s jaws, and accidentally lock themselves inside. They are forced to live inside the stomach forever and ever, until they suddenly think of crying for help through the T-Rex s vocal cords. This wakes up the T-Rex and as he yawns, they get out of his mouth and they climb up, only to see the T-Rex eat their house.
