Elf on a shelf is a magical tradition that brings joy to children and families during the holiday season. The elf is a mischievous character who hides around the house and reports back to Santa every night. The elf is here to watch over children and make sure they behave and follow the rules. Some families have fun with this tradition by creating elaborate stories about what the elf has been up to during the day, and children can even make gifts for the elf. The elf can also bring special surprises for children who have been extra good!
