Jackson Winstanley Sweettooth (or Jack for short) is a mouse who lives with Matthew and the rest of the Bailey family. He gets the blame for a lot of things – Mrs Bailey thinks he”s swallowed her ruby and nibbled at Shani”s birthday cake. And Jack”s biggest enemy is Beauregard Battersby-Bunge, the pesky ginger cat from next door. But everything gets better when another mouse, Blossom, comes to stay with the Baileys – soon Blossom and Jack are the best of friends!
