Three siblings, Rana, Polli, and Pada, are deciding what to do over breakfast. Polli mentions that in her dream, she heard about a treasure map hidden in their house. The first clue is "in a cave near the TV land." The three of them start looking for the first clue, which leads them to the second clue, till they find the treasure map. Once they find the treasure map, they see many fun and interesting places to go. Pada thinks they should go to the Pirate King's Island, and maybe they could find some treasure. That would help them get to the other places on the map. Once they get the island, they meet Lars the Pirate King. They visit with Lars for a while, and Lars gives them a tour of his treehouse. Including the room with all of his treasures. They loved his treehouse, and while they were at the very top. Lars told them to watch the sunset very closely because he felt the conditions maybe just be right for a green flash that day. He explains what the green flash is over the ocean. They noticed that it was getting late and they needed to get back home.
