Help! Santa is in trouble at the North Pole.

This is the message Tulip and her brother, Washington, received on Christmas Eve.

Tulip and Washington with Truffle their dog, set off from Santa's workshop for Mugsy Maldoom's digital-age toy factory, the Marvelous Mogadome, to find out why children everywhere want buffle-brained blimpkins for Christmas.

Will they be in time to stop Mugsy's wicked plan to take over Santa's job?
