Astrosaurs Academy 3: Terror Underground by Steve Cole
Another hilarious, action-packed adventure from the Astro-nomically popular Steve Cole. Young Teggs Stegosaur is a pupil at ASTROSAURS ACADEMY - where dinosaurs train to be ASTROSAURS. With his best friends Blink and Dutch beside him, amazing adventures are never far away. The astro-jet flying lesson ends badly for the cadets when they crash into a freezing cavern, deep underground! But there's more than rocks and ice for Teggs and the gang to cope with. It looks like some new enemies are trapped in the cold too . . .
