Christopher Pop-in-kins. He has 3 children and would get Christopher out every year. I love the whole story so back then I bought 2 sets one for my sister for her kids and one for me for my future children. They have since updated the doll and the book but I still love my original one. Christopher is similar to the Elf on the Shelf I think. He comes out after Thanksgiving to make sure the kiddo's are being good. When my niece and nephew were smaller I would call them up after Thanksgiving each year and tell them Christopher Pop-in-kins was just at our house so be on the look out. They were so cute and would yell to my sister "mom Christopher Pop-in-kins was just at aunt Linda's." It was so fun and my sister would always say how much it helped because the kids would behave until Christmas (ha-ha). I don't have the Elf on the Shelf but I love that this little elf has a name and can't wait to get Christopher out for Kyle each year as he gets older.
