Jack and Annie got to a shore where there was a pirate ship  in the far sea. Three pirates Pinky , Stinky, and Captain Bones caught Jack and Annie and forced to find treasure box. Captain Kidd's treasure. He was a Spanish captain and turned to be a pirate with some reason. He hided the treasure on the island. The Captain Bones showed the treasure map to Jack and Annie. Jack read the map to Bones. "The treasure chest was buried beneath the whale's eye."  The pirates took Jack and Annie into their pirate ship until Jack and Annie told the place of the treasure. From the ship, they found that the island looked like a whale. There was a big rock on the place of an whale's eye on the island which shaped like a whale. They told that they knew where the treasure was. So they went back to the island and pushed back the big rock and started digging. While they were digging the ground, a big storm came and the parrot came and said "too late" which made the pirates feel omen. So they went back to the ship giving up finding the treasure. Jack was curious about the treasure but the parrot said "too late. You should go back to the tree house." So Jack and Annie went back to the tree house and got back Frog Creek, Pennsylvania. After coming the Frog, Creek, the parrot turned to a beautiful old woman named Morgan le Fay who was a enchantress and a librarian in the time of Camelot. She said she would give  some mission for the sake of Camelot. Magic Tree House was magic. She chose them because Annie believed in magic and Jack's knowledge.
