In search of the perfect holly with shiny berries to decorate his
Christmas tree, Little Mouse begins to make his way home. Suddenly soft
white flakes begin falling all around him. "The sky is coming undone!"
fears Little Mouse. As he hurries home to tell Big Mouse his imagination
overwhelms him. First, he sees a "strange creature" waving its arms at
him as he passes the water. Then when he turns around he sees that an
invisible monster is leaving footprints right behind him! Finally, after
running circles Little Mouse arrives home only to find a giant "white
monster" in front of the door. When Big Mouse finds Little Mouse outside
he reassures him that the sky is not coming undone, but that it is
snowing; after explaining away lIttle Mouse's fears, he shows Little
Mouse that snow makes for a magical Christmas indeed.
