It's winter at Rose cottage and Christmas is fast approaching. But for Arthur and Lucy Mildew they hold out little hope of receiving any presents. Tumtum and Nutmeg have other ideas, however. Setting out for the home of Mr Toymouse, Tumtum and Nutmeg hope that he can spare a toy car and a box of magic tricks for Arthur and Lucy. But the crotchety old Toymouse who hoards his wonderful collection of toys doesn’t believe in sharing, and when the Nutmouses appear at his front door they are in for a nasty surprise. Once again, General Marchmouse and his brother officers must ride to the rescue and save the day. But can they get the Nutmouses out of this tight scrape and will Arthur and Lucy get their presents in time for Chrismas morning?
