Billy and the Mini Monsters: Monsters at Christmas

It's nearly Christmas and Billy and Ruby are feeling VERY excited. Billy has asked Santa to bring presents for his Mini Monsters and they're very excited too... until they try to help with the decorating and bring down the ENTIRE Christmas tree. Now the baubles are broken, the fairy is squashed and Billy's mother is feeling sad. Can the Mini Monsters make Christmas right again? And will Santa still come to them?
