Mister Rogers arrives with some large building blocks which he uses to build a tower, a street, and a car. He thinks about some young friends who used blocks and crates to make a pretend fire engine.
In the Neighborhood of Make-Believe, Mr. McFeely delivers some building blocks to the Platypus mound and Daniel is concerned that the blocks might be used to build « something bad. » When Lady Aberlin builds with the blocks, they start to dance around on their own. She and X the Owl (who is pretending to be a fireman) are amazed until they realize that Lady Elaine Fairchilde has attached strings to the blocks.
