It's the most wonderful time of the year!
Well, it would be, except Zombie has never heard of Christmas!
So it's up to Steve to plan a very Christmassy surprise with the most jolly mob of them all... Santa Creeps!
But when things go wrong on Zombie and Santa's magical Mooshroom sleigh ride,
Zombie and Santa must go on a quest to save Christmas!
Will they deliver all the presents in time, or will there just be empty mouldy stockings for Zombie's first Christmas?
