Jamie and Tom head off to Dino World to watch the Triassic sunrise. Above the noise of the screeching, buzzing dawn chorus, one sound is louder than anything else so the boys and their dino friend, Wanna, decide to investigate. The eohraptors that they find take a shine to Wanna and, while the boys are distracted, they lure him away. It's up to Jamie and Tom to find their little friend, but when they do eventually catch up with him on the clifftop, they realize they have a bigger problem-an enormous tidal wave is heading their way . . .
