Cartoon adventures of builder Bob and his friends Travis the tractor, Scoop the bulldozer, Lofty the crane, and Dizzy the cement mixer. Mr Bentley asks Bob to clear the roads with Scoop's snowplough, and while he is gone, Wendy gets a call from Farmer Pickles: the snow is threatening to make his roof collapse. Wendy and Jenny head over on skis, and Spud tries skiing but crashes into Scruffty's kennel. Bob arrives, and while he and Wendy work on the roof, Jenny builds a little igloo for Scruffty.
