Cassandra finally becomes fed up with Icarus' obnoxious behavior and claiming to be her boyfriend, telling him off during spring break in front of all their friends. Just as Icarus claims to be getting over her, the beautiful sorceress Circe (Idina Menzel) arrives in Greece, and soon all the guys are competing for her. Surprisingly, she chooses Icarus, but turns him into a platypus as soon as she reaches her island, bored of him. Hercules and Adonis go to see her, but also end up animals - a lemur and peacock, respectively. Meanwhile, Cassandra is missing Icarus and admits this to Helen; she then sees a vision of sorcery and realizes the trouble her friends are in. She and Helen go to rescue the boys, defeating Circe and breaking the staff she uses for sorcery. Cassandra still tells Icarus off as a boyfriend, but not as a friend. Helen meanwhile leaves Adonis a peacock despite learning how to change him back without a staff, to teach him a lesson about looking at other women.
