This is a tiny mechanical ghost that lives in young children's sculpts. If they are naughty during bathing time, he comes out and messes up their hair. Then they have to sit through their mother trying to comb them and it hurts. This ghost stays with the children until they are old enough to bathe and wash their hair themselves. He then leaves them and finds another child with hair to mess up.
Mine is still on my sculpt and he seems like he works all day.
I wonder when he sleeps.
