Andy meets the ankylosaur, the armoured tank of the dinosaur world, when he travels back in time 70 million years on a mission to replace a broken museum artefact. On his trip he must contend with two fearsome predators - a giant relative of the T-rex and a sneaky pack of velociraptors.

Andy jumps into his time-travelling clock and heads back three million years, where he runs into some ancient primates and joins their tribe. Along the way, he helps them fend off a prehistoric big cat, before having his trusty backpack stolen by some hungry vultures.
