Christmas; Mickey and Minnie are singing carols. Someone drops a basket on the doorstep that has what seems like hundreds of kittens; they quickly overrun the house. Mickey dresses as Santa, with Pluto as a reindeer, and brings gifts for the kittens. The kittens form a marching band, using kitchen implements; other kittens take saws, hammers, and other tools to the furniture. A kitten uses his toy steam shovel to drop a hot coal down Mickey's pants; two more come up with a toy fire engine. Mickey unveils the tree; the kittens swarm over it and strip it bare.
