Corydon the shepherd boy is a monster, a mormoluke, with one normal human leg and one goat leg. That’s why he was thrown out of his village, and that’s why he is picked up as a freak in a pirates’ sideshow. There he meets other monsters like him: the Minotaur, the Sphinx, the beautiful, tragic Medusa, and more. With the help of a magic staff, Corydon and the monsters escape from the pirates, but the gods of Olympus are united against Corydon and his friends, and it isn’t long before the greedy and cowardly Perseus is uniting the “heroes” of Greece into an army to wipe out the monsters. Corydon must journey into the Underworld to learn how to use the staff to save his new family, but what exactly does such salvation mean?
