Mister Rogers arrives with a box of batteries of various sizes. He demonstrates what batteries do by closing the curtains and using a flashlight. Mister Rogers starts to sing It's the Style to Wear a Smile but he is interrupted when Maggie Stewart stops by with some other battery-powered items. Sitting together in the kitchen, they demonstrate a battery-powered toy dog before they sing It's the Style to Wear a Smile. As Mister Rogers continues playing with other toys brought by Maggie Stewart, Mr. McFeely arrives on his new battery-operated delivery car. After trying out the new delivery car, Mr. McFeely and Mister Rogers take down the paper chain inside the house so that it can be delivered to the Neighborhood school. In the Neighborhood of Make-Believe, Neighbor Aber and Lady Aberlin try out a battery-operated car to be used for field trips. Meanwhile, at the school, the children choose to go on the field trip to learn instead of using James Michael Jones' learning machine. Back at the house, Mister Rogers concludes by singing It's You I Like. Part of the "Mister Rogers' Neighborhood" series.
