Mister Rogers arrives with an infant seat, describes how it is used to carry small babies, and fixes its broken buckle. He explains about laps and how they are used. At Bob Trow’s workshop, Mr. Trow shows a model of an infant chair. Bob Trow replaces an arm on a child’s rocker and practices talking like Robert Troll. In the Neighborhood of Make-Believe, Corney and Robert Troll make an infant seat for Prince Tuesday. They deliver the seat to the castle and King Friday finishes the seat. Prince Tuesday sits in the seat. When King Friday is left to watch the baby, he plays some sound games with him. Lady Elaine overhears and learns what little babies can do and decides that King Friday is a good father. Back at the house, Mister Rogers recites Lewis Carroll’s poem “The Jabberwocky.”
