Elf on a Shelf is a special toy designed to help Santa keep track of children's behavior throughout the year. He is only allowed to visit children's homes during the Christmas season, so he will return at the end of November. This year, he will arrive on November 29th and begin his annual task of keeping a watchful eye on children's behavior. If they are good, Santa will bring them toys and other gifts on Christmas Eve. But if they are naughty, they might receive coal instead!
