Pluto comes bounding outside to help Mickey get a Christmas tree. Chip 'n Dale see him and make fun of him, but the tree they take refuge in is the one Mickey chops down. They like the decorations, especially the candy canes and Mickey's bowl of mixed nuts. But Pluto spots them and goes after them long before Mickey spots them. Minnie, Donald, and Goofy drop by to sing carols.

Pluto is in the infantry guarding a pillbox from saboteurs.

Chip 'n Dale live next door to a zoo and spot the elephant's stash of peanuts. They go after them, but both the elephant and his keeper, Donald, are too clever. Then the boys realized the visitors throw peanuts, so they put on a song-and-dance act. Then they paint themselves white and pose as albino chipmunks.

Donald has a ride-on sized train layout in his backyard. There's a large tree (home to Chip 'n Dale) that's out of scale, so Donald moves it while they're out; they come back to see their tree moving. No problem; one of Donald's model houses is just their size.

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.

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 flies his model airplane into Chip 'n Dale's tree. Dale climbs in and proceeds to cause trouble.

When Donald Duck chops a Christmas tree, the inquisitive chipmunks Chip and Dale follow and see him decorate it with nuts and sweets. So they sneak in his home, determined to 'harvest' it all, using the toys for the Duck nephews, as if Christmas came early for them, so to say. Donald puts up an equally 'playful' yet grim defense, so it all rapidly escalates into a bitter miniature two-to-one-giant war over the Christmas-treats.

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.

Donald's playing lumberjack, but the targeted tree just happens to be the home of Chip 'n Dale. They give Donald plenty of trouble cutting down the tree, but eventually he succeeds. The wily chipmunks, though, manage to get their revenge on the homewrecker.
