Have you seen the ELF ON THE SHELF books and shelf that you can purchase at gift shops? I have seen them at Hallmark and also at Barnes and Noble. It follows what many people have posted...the elf moves around each day and reports to Santa at night. It comes with the little elf, the book and a green shelf. It's a little pricey, but very cute. I wish my kids were still little so I could justify getting one and using it during the holidays! ;)
