During a Magic Street Performance, Hector and Jessica watch a street magician named Calvero transform himself into a snake—but before Marlon, his assistant, can change him back, Danny Rebus steals the magician's book and turns Jessica into a lizard. When the Electric Company seeks out Danny, he turns himself into a turtle. They have one hour before they change into reptiles forever. However, the magic book is locked up, and there's only one way to get it out.
