As the title implies, the three blind mice are musketeers. The cat sets a number of traps for them, which they all evade (apparently without realizing it) while he sleeps. The cat eventually wakes up and begins chasing them unsuccessfully, thanks to their teamwork.
Donald has to get up early, but everything seems to be working to keep him awake. His loudly ticking alarm clock resists several attempts to quiet it. Donald ultimately swallows it; the glow-in-the-dark dial can be seen through his feathers. Then his folding bed folds up on him. Springs start popping out of it; Donald builds an elaborate framework to hold it down. Finally, enough of the clock reassembles itself to sound the alarm and night is over.
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.
Mickey is performing routine maintenance on his tugboat (with interference from a pelican) when a call comes on the radio that there's a sinking ship needing assistance. Sadly, Mickey's crew consists of Donald and Goofy, so getting underway to help is not easy. Goofy has to fight a boiler's door to get it stoked with coal (and when he succeeds, he overfills it) and Donald gets tangled up in the machinery. Not to mention that nobody casts off, so they drag half the dock along with them. The overworked boiler soon explodes.
Mickey wants some of the cake Minnie has just baked, so he offers to clean up her yard. As he's working, a tiny tornado (smaller than him) with a mind of its own comes along and causes trouble. After Mickey finally chases the little twister off, it gets its big brother, which makes a grand mess of the yard. Most of the cartoon, except for the opening and closing, has no dialogue.
Two Dutch children stumble on a clearing in the woods where gnomes are going about their business. The gnomes are friendly to the children. A witch comes and takes them away on her broom to her gingerbread house, where she turns nasty on them, turning the boy into a spider, her yowling cat to stone, and tries to turn the girl into a rat when a gnome's arrow stops her. While the gnomes are fighting the witch, Hansel and Gretl free the other children who have been imprisoned and transformed by the witch.
Donald Duck's gluttonous cousin, Gus Goose, comes for a visit and practically eats him out of house and home. When the direct approach to getting rid of his voracious houseguest fails, Donald resorts to desperate measures to dislodge him.
Mickey's a shovel operator and laborer at a construction site; Minnie is delivering box lunches; Pete is the foreman. Mickey pays more attention to Minnie than to his work, and keeps having accidents (mostly involving the blueprints Pete is holding). Pete steals Mickey's lunch, so Minnie offers him one on the house. While he's eating, Pete kidnaps Minnie; Mickey fights him, but the tide turns when Minnie dumps a load of hot rivets into Pete's pants...
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.
Mickey is heading out on vacation from Burbank to Pomona, taking the train. The conductor, Pete, won't let him on with Pluto, so he hides Pluto in his suitcase, and tries to hide him all throughout the trip without much luck. But Pete wins when Pluto is hooked by a mail hook. Or does he?
With a rubber bone as a lure, Donald Duck tries to entice Pluto to try his mechanical dog washer. When the bone gives Pluto trouble, Donald tries a toy cat as a lure only to unexpectedly fall into the washer himself, get scrubbed and then hung out on the line to dry.
Donald's sister Dumbella sends her three sons Huey, Dewey, and Louie to visit their uncle Donald. They prove to be quite a handful for Donald, even with help from his book on child rearing.
