My girl, Jiji, (resin, SD Dragon Doll Xixi) has fingernail polish, brick red scribbles, and ever time I looked at her, the bits on the end of her nails were all 'nibbled' off. I thought it was just because of changing clothes or something. But then I touched up her nails and left her on the sofa on her shelf for about a week and checked again. Nibbled.

So I took all the paint off, redid her nails again and told her to knock it the heck off, it's a bad habit, and if she kept it up, no more nail polish (yes, I talk to my dolls, and other inanimate objects that don't obey me, like my car on a cold morning).
She hasn't nibbled her nails since. What the heck?

So what's your strange doll thing?
