Captain Teggs is no ordinary dinosaur - he's an astrosaur! On the incredible spaceship DSS Sauropod, along with his faithful crew, Gypsy, Arx and Iggy, Teggs rights wrongs, fights evil and eats a lot of grass! The astrosaurs have picked up a distress call from an unmarked spaceship near the Carnivore Zone. It seems to be empty. Teggs and Gipsy go across to investigate - all they find is a royal crown and various bits of regalia - marked with the crest of carnivores. Arx warns them that a huge ship is approaching. A bunch of terrifying T. rexes enter the ship! There's an exciting chase as Teggs and Gipsy try to get away, but they are trapped. These T. rexes belong to the Royal Guard - and accuse the astrosaurs of stealing the Crown Jewels of King Rex-Rex! Can the astrosaurs clear their name and save themselves from the T.rexes?
