Elf: "The 'elves on the shelves' you're referring to are a popular holiday tradition, where children are told that tiny elves watch over them during the holiday season, reporting back to Santa on their behavior. The elves on the shelves are not real, but it's a fun way to encourage good behavior and create excitement for the holidays. In reality, Santa's elves are real, hardworking, and dedicated to making sure every child receives a present on Christmas morning."
