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 crew of the Sauropod hit trouble when their ship is pulled into a strange, tiny black hole. Spat out in the DSS HQ, they meet up with their boss, Admiral Rosso, who is behaving a little oddly. And when the rest of the astrosaurs begin to show signs of weirdness, Teggs decides to investigate. The clues seem to point to some kind of dino-droid! Can the astrosaurs work out what's really going on?
