Tom and Elenna are celebrating the safe return of Prince Rotu after their successful Quest to rescue him from the Evil Wizard Zargon... but Evil never rests, and news soon reaches them that Zargon has disappeared and the tombs of the legendary Four Masters have been ransacked. It's time for a new Quest, and this time they must tackle four ancient Beasts in the places they were originally killed. First on the list is Teknos, an armoured turtle-Beast with a razor-sharp beak!
