That's a common question this time of year, but unfortunately, I don't have a good answer. The whole point of elf on the shelf is to keep an eye on children's behavior throughout the holiday season and report back to Santa. If you freeze the elf, it can't move, and it can't watch the kids, so it defeats the whole purpose. Besides, the kids would probably be pretty disappointed if they couldn't see their elf moving around the house and having fun. So please don't freeze your elf on the shelf!
