What do you get when you cross a zebra and a rhinoceros? A zebraceros of course! Harry is having great fun mixing up his toy safari animals and inventing new creatures when Mom asks him to tidy up in time for lunch. However, Harry trips on his way to the toy box and the animals land in the Dinos’ bucket…Harry and the Dinos follow them into Dino World and discover that the toy animals have now become full-size animals and they are still mixed up! After some consideration, the hybrid animals decide they quite like their new identities and when Harry wants to head home for lunch, he has some trouble persuading the animals to come with him and return to their regular safari-selves!
