Bert, Ernie, and other muppets, including Grover, Oscar, The Count, Betty Lou and Cookie Monster, spend the night in a strange house where each room is decorated in a different color. They were not especially gruntled by their accommodations: Cookie Monster longs for a green cookie to go well with his green room, while the Count von Count does not like his red room (not one little bit of it), Ernie is not too thrilled with his purple room, Oscar the Grouch finds himself trapped in a bright pink room, filled with flowers and hearts, while Bert longs for a beige room over an orange one, Betty Lou is blinded by yellow, and even Grover finds himself depressed by his matching blue room. They rapidly depart the next morning, happy to leave the weird house of seven colors and return home to Sesame Street. The Sesame Street residents are unaware that the House of Seven Colors is in fact a tourist attraction, frequented by vast car and busloads of monsters who feel right at home in rooms that match their fur.
