Donald makes a scale model railroad on his property of everything. However, he also gets rid of Chip and Dale's tree when it isn't like the minature trees he planted to be in scale. Chip and Dale try to get even by living in minature scale model houses and doing other acts to annoy Donald. In the end, when their tree has a hole in it and ends up on the railroad track, Chip and Dale take advantage of this to say it is a scale model of California Giant Redwood with a tunnel. Satisfied with the explanation, Donald rides his train through the tunnel and leaves Chip and Dale alone from there on.
