Natroll

Natroll is a very rare species of magical and living female wooden doll.

You can find them when ripping any kind of piece of paper from any kind textbook in the very dark place. (Don't try this!).

Legend said she will hunt anyone who read books too fast. (Mostly they wanted to play video games, but instead they were forced to read books).

For little kids until early teens, she will only say "hi" to you many times (?). But if the target(s) older than that, then it will be different.
