Being the son of a mythological Greek god can have its advantages, as we see in a new clip from the upcoming sequel Percy Jackson: Sea of Monsters. When Percy (Logan Lerman), Annabeth (Alexandra Daddario), and Tyson (Douglas Smith) need help reaching a ship at sea, Tyson calls upon his dad Posiedon, who summons a mystical and colorful beast known as the hippocampus to help them on their journey to save Camp Half-Blood by retrieving the Golden Fleece. Watch the latest scene from director Thor Freudenthal's fantasy sequel, in theaters August 7.
