Rogers has brought three planks of wood to complete a play building made from big blocks. The planks become the roof of a house. Rogers says he played with all kinds of toys and pretended all sorts of stories. This leads to the standard six NOM models set up in the kitchen.
In the NOM, King Friday implores Lady Aberlin to don the Trolley with a sign: "No Play Allowed." She nails copies of the sign around the Castle. The nailing is Lady Aberlin's way to prove she is angry. X and Henrietta are understandably upset. X wonders what Lady Elaine feels about it. At the Museum-Go-Round, Lady Elaine wants to show her block building to Lady Aberlin, who explains the new ruling. Lady Elaine protests to King Friday that everything in her place is play. She will not live in a neighborhood without play. Before Lady Aberlin can reason with her, Lady Elaine whisks herself and the Museum elsewhere. All that remains is a sign: "No play, no stay." The Museum appears in a sunny place, right in the midst of a marching band competition. Then she pops us in a theater, during a stage play. Finally, the Museum turns up in a play park. There, Lady Elaine meets an old friend, Barbara.
Back at the television house, Rogers takes the model Museum away from the setup, then the Platypus Mound, the Clock, and all the other models. He says we can always remember where something was. He shows an undercranked film of people moving a house from one place to another. He manipulates his block house, putting in a window and then removing one set of blocks to make a back door.
