How does Santa really know whether a child has been naughty or nice? The elf answers the age old question in "The Elf on the Shelf: A Christmas Tradition."

The Elf on the Shelf: A Christmas Tradition is an activity the entire family will enjoy - and one that is sure to come back year after year. This cleverly rhymed children's book explains that Santa knows who is naughty and/or nice because he sends a scout elf to every home. During the holiday season, the elf watches children by day and reports to Santa each night. When children awake, the elf has returned from the North Pole and can be found hiding in a different location (yup - that's where you come in as a parent - you get to find a new spot each night!). This activity allows The Elf on the Shelf to become a delightful hide-and-seek game each and every morning.

Each box comes with its very own scout elf that easily sits on a shelf or window ledge, a hardbound children's book and a keepsake box for easy storage. In addition, each shipment is marked for "Special Delivery" from Santa's workshop.
