Rogers assembles a mobile of fish. He follows the instructions printed on cards. He goes to Sea World of Ohio to see Mike Scarpuzzi, who trains Shamu the Killer Whale. Mike explains the care they give to Shamu and their large amounts of play time. Rogers and Scarpuzzi see Diane, who is nearby another killer whale, Namu. Together the four of them show Rogers some of their act.
In the NOM, Miss Paulifficate hangs a crown mobile someone sent for King Friday XIII. Mr. McFeely gives Miss Paulifficate, Queen Sara, and Lady Aberlin invitations to join "Dance Mistress" Lady Elaine at her new dance studio in the Museum-Go-Round. "Come learn to dance at the Always Happy Dance Studio." Already the three invitees are puzzled that King Friday did not get an invitation. Neither did X or Daniel. Thus Lady Aberlin is reluctant to join the Studio. She goes to the factory, where Chuck Aber tells her the Dance Rocket is missing. He also says he did not receive an invitation to the Always Happy Dance Studio. At the Museum-Go-Round, Lady Elaine says she took the Dance Rocket, thinking Corny made it for her studio. She also says men don't dance. Aber and Lady Aberlin dance their way back to the factory.
Back at the television house, Rogers says that all sorts of creatures dance. He shows a film (video, really) of fish seemingly dancing through water.
