Join some very enterprising mice in this mini hardback edition of the fun-filled festive book from best-selling creator of the Percy the Park Keeper Books, Nick Butterworth.

How can they stop him from spoiling everything? Their friend, the wise rat, Ton Chee, has an idea involving a little golden bell ... but will it work?
