One prisoner, a scrawny T. rex named Thickhead McBrick, made a deal wih Fangetta and her boyfriend, a judge named Braxus: he'd sell the T. rex Crown Jewels that he had recently swiped from King Groosum and give them part of the profits if they set him free. The trio managed to frame Teggs and Gipsy for the crime using Braxus's spaceship and some fake jewels made by Fangetta, who lured the DSS Sauropod to the scene using a recorded distress call. The T. rexes then sent them to Fangetta's prison, where the inmates tried to eat the astrosaurs and robot T. rexes took them to the crooked governor for punishment. Fangetta decided that they would be eaten during King Groosum's royal feast to celebrate the Crown Jewels' return.
