Animated adventures with builder Bob and his friends - Travis the tractor, Scoop the bulldozer, Lofty the crane and Dizzy the cement mixer. Bob is building a shed in Farmer Pickles' field while Wendy whitewashes his farmhouse. Wendy lets Spud help with the whitewashing, but a string of disasters ends with a wall being painted bright red. Bob suggests that he and Wendy swap helpers. Dizzy mixes what is left of the whitewash with the red paint, giving the farmhouse a coat of pinkwash.
