Mister Rogers' Neighborhood (1968)

S6E39 Episode 39

Rogers introduces various potato types and demonstrates their reactions when soaked in water. He even creates a catchy tune about potatoes. Mr. McFeely arrives with a special delivery: an ocarina. At Negri's Music Shop, a bluegrass band practices, sharing insights into their unique musical style. Chef Brockett takes a turn with the ocarina and chooses to portray a potato bug in the upcoming opera. Meanwhile, John Reardon and Lady Aberlin continue their preparations but still need a king and a pilot. King Friday decides he won't participate, while François Clemmons is suggested for the king's role, and Miss Ito is chosen as the pilot.
