Mister Rogers arrives and quickly moves into the opera which has been planned throughout the week. The opera is to include various components from the previous four episodes and will focus around "Spoon Mountain." The opera opens with Joe Negri playing the part of the Storyteller as he sings an introductory tune. The royal family of King Kittypuss, Queen Mumsiebelle, and the Prince Extraordinary (played by Chef Brockett, Miss Paulificate, and Chuck Aber) are deciding who will celebrate a birthday today. After it is determined that it will be Queen Mumsiebelle's birthday, Kittypuss' surprise gift to her is a mountain -- Spoon Mountain. As the royal family is dancing about, Betty Green of the park service (Lady Aberlin) interrupts with the news that a Purple Twirling Kitty was climbing to the top of Spoon Mountain but is being held captive by the Wicked Knife and Fork who is demanding ownership of Spoon Mountain. The Prince and Betty Green set out determined to help the Kitty. At Spoon Mountain, Prince Extraordinary and Betty Green buckle together as they begin scaling the mountain. Nearing the top, the climbers are welcomed by Commodore (Officer Clemmons) to Balindore -- a door on the mountain which leads to a resting place for travelers serving a hearty meal of fresh popcorn. With a bowl of popcorn, the two rescuers tune into a newscast (by Reardon) and learn that the "siege on Spoon Mountain [has grown] more serious... [as] Wicked Knife and Fork has put Purple Twirling Kitty in chains in order to keep him on the mountain." Purple Twirling Kitty (Jeff Shade) pleads to viewers for help as Wicked Knife and Fork (Bob Trow) continues his demand for Spoon Mountain. Extraordinary and Betty depart Balindore with the support of Commodore. After singing a song of appreciation for Betty Green, Prince Extraordinary and Betty reach the top of Spoon Mountain where they encounter Wicked Knife and Fork and learn that Purple Twirling Kitty has been hidden. As they find Purple Twirling Kitty, Wicked Knife and Fork attempts to capture the Prince and Betty as well; however, his efforts are cut short with the arrival of Commodore. Wicked Knife and Fork reveals that all he ever really wanted was a spoon. The entire group returns to the castle where some of Wicked Knife and Fork's knives and forks will be melted into spoons. Celebrating the Queen's birthday, Prince Extraordinay and Betty Green share the news that they are in love and will soon marry. Wicked Knife and Fork also declares that he will change his name. Back at the house, Mister Rogers reviews the themes of love found in Spoon Mountain -- "From the outsides of people, you certainly can't always tell what's in their hearts. There's so much more to everyone you meet than will ever meet your eye. There are wonderful surprises in all of us." Part of the "Mister Rogers' Neighborhood" series.
