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.

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 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.

Donald takes a kayak trip. When he gets to his campsite, he unloads the kayak, fights with his folding chair, and goes to sleep. Meanwhile, the chipmunks of the forest (precursors of Chip 'n Dale), attracted by his squawking, make off with the huge pile of food he carelessly unloaded. They get the attention of a bear, who Donald is soon battling.

Donald Duck tries to exhibit his golfing ability to his nephews only to have them tease him with sneezes, noises and "trick" clubs. Finally, they put a grasshopper in a ball and it "jumps" all over.

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's doing a little tree surgery when he spots Chip 'n' Dale gathering nuts. He saws off the branch outside their hole and paints it with tar, which Dale gets stuck in. Then Donald has a little fun with the long-handled pruning shears.

A baby lamp finds a ball to play with and it's all fun and games until the ball bursts. Just when the elder Luxo thinks his kid will settle down for a bit, Luxo Jr. finds a ball ten times bigger.

Farmer Donald goes through his farmer day until a fly causes him to lose control while milking a cow.

Jasper is given an ultimatum by his master: break one more thing and you're out. Rodent Jerry does his best to make sure that his tormentor "gets the boot".

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.

Donald and the chipmunks, Chip and Dale, are after each other again, this time when they come upon Donald vacationing in a trailer. When he goes swimming, they fool him by moving the diving board and end up wrecking his car.
