Test Pilot Donald

It's October 7th and Chip is working industriously to store enough acorns in the tree for the winter. Dale would rather sleep in his matchbox, but an angry kick from Chip gets him working furiously. But there's only so much they can do. Their tree is nearly out of acorns. Luckily, the two semi-intelligible chipmunks happen to see the half-unintelligible Donald Duck, a park ranger, planting acorns. They immediately set to steal his bag of the precious nuts. Donald soon realizes what they are up to, and sets out a box propped up with a stick. It's a crude trap, with an acorn as bait; but it's not too crude to fool Dale, who upsets it and traps Chip. Soon, Donald finds he can have fun instigating a fight between these two quarrelsome chipmunks, but he underestimates their friendship and their ability to work as a team against a common enemy: in this case, a bad-tempered duck.

Donald is shoveling the snow off his walk; Chip 'n' Dale are shoveling their branch. Donald tricks them into shoveling his walk. Angered, they sneak into his house, where he's getting ready to make popcorn. They've never seen this before, but they love it. They stow away in the box, then make off with the bowl of popped corn.

While streetworker Mickey romances Minnie, Mickey's nephews Morty and Ferdie take control of his steamroller and it's full speed ahead on a very destructive ride.

Donald needs a log for his fire. Unfortunately, the one he picks is occupied by a couple of chipmunks and their stash of acorns. When he cuts it down, Chip and Dale fall out, but their acorns stay behind, so they work at putting out Donald's fire and retrieving their stash. Donald, of course, takes this as calmly and cheerfully as you would expect.

Donald steals Chip and Dale's nuts for his nut-butter shop, which is shaped like a giant walnut, Chip and Dale, roll and "shoot" Donald into a nearby lake.
