When a huge snowstorm leaves everyone stranded, Mickey and all of his guests at the House Of Mouse, including Pooh, Piglet, Belle, Snow White, Ariel and many more of his old and new friends, break out the cookies and hot chocolate to help Donald mend his tattered Christmas spirit. The fun starts when Minnie pulls out their favorite holiday home movies and everyone starts to reminisce. As everybody lifts their voices in joyful song, they realize that the "Best Christmas Of All" is the one you share with all of your friends!
