Don't go to the dentist on Halloween.

Parents always scare Russian children with Baba Yaga. If you do something wrong, Baba Yaga will come. I was always afraid that she would turn out to be my dentist.

One of her eyes is blind - she looks into the afterlife with it. And her leg is made of bone, well, in my case, it's an arm.

who is not a good boy?
