On the way to Viridian City, Misty notices that Horsea isn't feeling well. She decides to take Horsea back to the Cerulean City gym to get a chance to swim around in their bigger pool. Her sisters get an idea to generate publicity for the gym by having an underwater ballet. To everyone's surprise, they picked Misty to be the star of the show. They begin the show. Misty swims around a little with the Pokémon as they tell the story. She swims into a hidden area for a desperately needed breath of air, and goes back to the audience. Then, it's time for everyone in mermaid land to go to sleep. The large shell closes on Misty, and gives her the chance to take out a breathing device while no one is looking. Team Rocket tie up the two sisters who were to play the villains, and replace them on stage. Jessie dressed as a male dancer, and James in a ballerina costume. They try to steal all the Pokémon, and are defeated by Ash and Pikachu as usual. The crowd believes that the entire attack was staged and applaud the show. The show was successful in generating publicity for the gym, and everyone is lining up to buy tickets to their next shows. Misty leaves Horsea and Starmie with her sisters, and the group continue onward to Viridian City.
