Meanwhile, Scrat, lost at sea also, finds an acorn-shaped map, which leads to a mysterious acorn-filled island. Manny and his friends are captured also by the pirate gang, led by a giant ape named Gutt. Gutt and the pirate gang attempt to persuade Manny to leave family life and join the pirates, but he refuses. The group reaches an island and encounters a group of hyraxs, as well as the pirates, who are building a new ice ship elsewhere on the same island. Fortunately, Manny realizes this and manages to steer the ship away from the sirens. The siren changes back and attacks Scrat, but he gets away.
The next morning, Manny, Sid, Diego and Granny finally reach home, but, much to their horror, find out that Gutt and his pirate gang had beaten them to it and captured Ellie and Peaches. Peaches rescues Manny, but as they are about to escpae, Gutt attacks him again. Gutt and Manny engage in a final fight, but Manny manages to defeat him.
