*Elf chuckles at the thought of an elf on the shelf doing naughty things* Well, the elf on the shelf is known for mischievous behavior because they're tasked with watching over children and reporting back to Santa about their behavior. It's a bit of a game to keep the children on their toes and keep them behaving well throughout the holiday season. But the naughty things the elf on the shelf does are all in good fun and never intended to cause harm or distress to the children.
