Chongo has discovered a ship anchored off the island. He, Morgan and Link run to the beach where they find Mu-tan and his pirates. They scare them off and rescue Dr. Hayden and Leslie. Morgan tells Dr. Hayden he had found a boat off an inland island along with some maps and other articles. Dr. Hayden feels that these articles and maps belong to his brother, Philip, who was lost near the islands some years before. They decide to go back to the cave and take a look at the map so they can start their search right away.
