Meet Jask Skellington. He's in charge of making Halloweenland the coolest creepy place around - and he's bored. Searching for new ways to celebrate, Jack finds Christmas Town - and a whole new festival! Christmas, Jack decides, is just what Halloweenland - and the world - needs. He sets out to take over the role of Father Christmas in his own inimitable style - but is the world really ready for a skeletal Santa?
