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.
Toy Tinkers
Chip and Dale sneak into Donald Duck's house to steal his walnuts. Donald dresses as Santa Claus to have fun with the two thieving chipmunks, but ends up using the war toys underneath the Christmas tree to do battle with them.
