It is weirdly popular with the kids, I really dont get it but both my neices were into the idea (they are 7 and 9 years old)
I guess it helps that my brother and sis in law actually did good stuff with it instead of weird/creepy stuff like moving shit around. My sis in law baked cookies in the middle of the night a few days before Christmas just so she could put them out with elves.
My youngest neice was SUPER hyped that her elves "made cookies" for everyone.
Great if it makes the kids happy.
I checked the google images and people do dumb shit with the elves. REALLY dumb shit.
