Here is the Liéchi. It is in Slavic mythology, a spirit of the forest and the trees. He is the guardian of the forest and its inhabitants. He can change size, transform into a tree, transform animals into plants, sometimes kidnaps children and women ... O_o Rather blue in color, he wears animal skin clothes and is often considered by the populations like bad. But to calm him down and, as a sign of respect, if he is offered a gift via a stump then he will never hurt you.

Hope you gonna like it.
