The ship sails into the Great Unknown and encounters sirens who hypnotize everyone except the Scotsman who is conveniently immune thanks to his musical taste for Scottish music and his wife's singing. The entranced crew bring the ship to ground and give the sirens all their treasure as the Scotsman confronts the Sirens. They send the crew against him but he uses his bagpipes to snap them out of it. While the Sirens attack the defenseless Scotsman, Jack grabs his sword and kills the beasts. When the other ships leave without them and they have to have a series of contests to determine who will row the boat. Jack wins them all, including an epic thumb-wrestling battle.
