Jamie and Tom are off on another adventure in Dino World and with their little dinosaur friend, Wanna, they set off for Misty Mountains. They spot a group of turkey-sized dinosaurs on the mountainside - they look really cute. But when the dinos chase after a passing lizard the boys realize they're not so sweet after all. They're carnivores and they want Jamie and Tom for their next meal! As they race to get away the boys and Wanna climb further up the mountain but a sudden tremor stops them in their tracks. It's not a mountain at all - it's a volcano ...and it's about to blow!
