Felix Marigold takes his pet croc to Bring Your Pet to School Day! What could go wrong? Two best friends, a croc who thinks he’s a puppy and four evil Caitlins. Felix Marigold is given an extraordinary pet to look after by his eccentric Aunt Opaline (who also happens to be a brilliant scientist). He quickly discovers that his pet is a baby crocodile! However, Jupiter is no ordinary croc. Together with his new best friend Autumn Black and her pet ferret, they must figure out why the most dangerous animals on earth are behaving like puppies, while trying to avoid the four Caitlins, who are intent on exposing Jupiter and sending him back to the swamp where he belongs. Will the Caitlins ruin everything?
