Teggs Stegosaur is a brand new pupil at the Astrosaur Academyy where all astro-cadets go to complete their training. He hopes to become an ASTROSAUR one day but for now he has classes to attend, missions to complete and lessons to learn. His new best friends and roommates, Blink and Dutch, are always his first choice for fun - but also to work with on his homework!
Together they make a great team - the Daring Dinos! Teggs and his friends are going to be the youngest contestants in the Megasaur challenge! Robot-Boxing, Rock Tennis and Weight Lifting mean the Daring Dinos can show that they really are the best, strongest and bravest Astro-cadets.
But the Megasaur challenge turns out to be mega-unlucky and lots of contestants keep getting 'accidentally' hurt. Will Teggs and his friends be hurt too? Or will they discover who's behind all the problems at the contest before it's too late?
