what does the elf on the shelf do

The Elf on the Shelf is a popular Christmas tradition where an elf doll is placed in a home and moves around at night to keep an eye on children and report back to Santa about their behavior. In the morning, the elf returns to its original spot, and children wake up to find it in a new location. The idea is to inspire good behavior in children because the elf is a magical helper who will relay any naughty actions to Santa before Christmas Eve. The tradition is a fun and unique way to add a bit of magic to the holiday season.
