Elf on a Shelf is a fun Christmas tradition where a small elf figurine is placed in different locations throughout the house, often in silly or mischievous positions. The idea is that the elf is watching the children's behavior and reporting back to Santa Claus each night. To find Elf on a Shelf, look in common areas like living rooms, bedrooms, and kitchens. You may also find the elf hiding in the most unexpected places, such as inside cabinets, on top of furniture, or even hanging upside down from the ceiling!
