Mission Odyssey Episode 9

Poseidon makes a deal with the Gorgon sisters to grant them eternal life if they defeat Ulysses. In their attempts, they turn Titan, Diomedes and Zephyr into stone and also seem to be able to control their statues like puppets as they did with Titan and Diomedes. After Ulysses defeated the Gorgon sisters, his three friends were restored to normal, along with everyone else the Gorgon sisters have turned to stone.
