Mister Rogers is dressing up as a pilot for the costume party. He talks about how he used to pretend to be a pilot when he was young and then really learned to fly planes when he was older. Betty Aberlin and Joe Negri arrive in their two-person horse costume, followed by Francois Clemmons and someone in a giraffe costume. After discovering that it is Chef Brockett inside the giraffe costume, the Neighbors enjoy a snack and try to guess what costumes will be worn in Make-Believe. In the Neighborhood of Make-Believe, everyone is dressed in their special costumes — everyone except Ino A. Horse who prefers not to wear a costume. When a hot air balloon lands, everyone thinks that it is Lady Elaine Fairchilde and Corney dressed in costume as the Platypus family. Elsie Jean is clearly upset when she thinks they have been forgotten. Realizing it really is Dr. Bill and Elsie Jean, everyone is delighted by their return and retires to the castle’s C Room. Back at the house, Mister Rogers reflects on the week and sings I’m Proud of You.
