Mister Rogers puts on an old shirt to protect his clothes while he plays with sand. Chef Brockett brings over a new cookie he has made. In the Neighborhood of Make-Believe, Mister Rogers and Mrs. McFeely try out some of Corney’s chairs because Corney is having a sale. A purple something drops out of the sky and Mr. McFeely takes it to Lady Elaine. It is a disk that answers questions about the Planet Purple. This informs them that all boys on the Planet Purple are named Paul and all girls are named Pauline. The purple platter also tells them that all chairs on the planet purple are the same. Lady Elaine tells Chef Brockett that all the food is purple on Planet Purple. He takes cookies to everyone in the Neighborhood of Make-Believe, but Lady Elaine has decided to only eat purple things.
