The King requests Captain Flinn and his crew's immediate presence on His Majesty's Royal ship. He tells Flinn that his ship was raided by 'those beastly pirate dinosaurs' who stole his crown, his jewels and his throne. He needs Flinn to catch the pirate dinosaurs and get them back. Suddenly a young pirate makes an attack on Flinn. The King introduces his son as Prince 'useless'. Actually, the kid corrects himself it's Prince Eustace. He patiently explains that these are the 'goodie pirates' and they're going to catch the baddie pirates. Eustace resolves to help them. The King orders that the Prince be locked in his cabin. But lo and behold, the young Prince fires himself from a cannon onto the Acorn. He's here to help. 'How much trouble can a small boy be...?', wonders Flinn. He can stay. But Flinn soon learns exactly how much trouble a small boy can be as Eustace runs amok on the ship, spinning the wheel, swinging from the rigging and generally rocking the boat.
