In this sweet story now available in board book format, it's Christmas Eve, and Big Mouse and Little Mouse are decorating the tree. Little Mouse notices that they don't have any holly, so he sets out to find some. It begins to snow, and Little Mouse is scared that the sky is coming apart! Then he sees his reflection in the pond and thinks it's a monster--and when he runs away and discovers paw prints behind him (his own), he thinks the monster is chasing him! Can Big Mouse show him that there really is nothing to be afraid of?
