While Perseus tries to find a way to conquer the Kraken, Pegasus is captured by Calibos' henchmen. Zeus commands Athena to give her owl Bubo to Perseus, but she convinces the gods' blacksmith Hephaestus (Pat Roach) to create a golden replica instead, who leads Perseus to a trio of hags called the Stygian Witches (Flora Robson, Anna Manahan and Freda Jackson), who have one tooth and eye between them. By taking their magic eye, Perseus forces them to reveal that the only way for the Kraken to be killed is by killing the gorgon, Medusa, who lives on an island at the edge of the Underworld. The group continues on their journey, minus Andromeda and Ammon, who return to Joppa.
