Zeus is a hamster who rules over the Olympian gods, who are pets in an animal shop. Demeter, a little cricket, assists Zeus as he investigates the maze below the Olympian shop. Athena, the cat, and Ares, the dog, prowl around to find clues about how to defeat the blazing minotaur whose heat is making the entirety of Olympus swelter and sweat. But it is Poseidon, the ruler of the underwater kingdoms of fish tanks, who takes charge just when the Olympians are ready to give up.
