As the group continue through the Orange Islands, they notice a Nurse Joy whizzing by in a kayak. They decide to follow it. They come to an island, and see a huge Magikarp. It is flopping around and Nurse Joy comes by to give it some calcium, then she throws it back in. Ash is hungry so, Nurse Joy invites them over for lunch. They then go for a kayak ride, except she gets too far ahead of them and when Ash, Misty and Tracey catch up they see her kayak empty, and get worried. They see a pink figure floating up, thinking it's Chansey, except it's really Jigglypuff, who they got away from before it sang. When Nurse Joy and Chansey pop up from helping a sick Cloyster, she invites them underwater to see her look it over. Ash begins to run out of breath and tries to get back above water, but can't because a Dewgong decides to start playing with Ash. They make it out okay, and back at the cabin, Nurse Joy tells them her story about when she found a sick Magikarp and decided to take care of it. She then decided to treat Pokémon around the islands rather than just work in a Pokémon center. She goes out to help some sick baby Seel as a hurricane is starting. Tracey goes out and Ash and Misty follow, they want to help her, but got washed out and she had to save them. After resting on a beach are trapped by Team Rocket. Magikarp comes to save them, evolves into Gyarados and beats them. They go off to help the baby Seel and are on their way to Navel Island.
