They go to the ocean, and goes into the water, Finn was afraid at first, but then, he became calm, as Jake told him to, and had now overcome his fear of the ocean. They go deeper, and see fishes, whales, octopuses, and turtles. When Finn said he had enough, a Mermaid Lady stole their "Going-Up String Bag", and went away.
They searched high, and low, but couldnt find the Mermaid Lady. At last, they found the Mermaid Castle, where they see the Mermaid Lady.
