Tell about legendary creatures in your country.

One of the most popular legendary creatures in Russian fairy tales is Baba Yaga. She is an elderly lady living alone in the forest skilled at witchcraft, but never uses it to improve her looks, though people in general think she is a bit scary. Maybe the reason is her smile, she has few teeth and only one of them is visible, no matter how broad is her  smile.

 Also, she has constantly been fantasizing of eating young Russian princes and even children, presumably, cooked as meatballs. To my knowledge, she has not committed an act of cannibalism yet. Possibly, she is too sentimental for it: when princes or common Russians meet her during their quests, have a sauna and dinner at her place, then tell her all about their problems (usually something concerned with captured princesses or siblings), she loses her appetite and even helps them to achieve their goals. She is capable even of risking her long-standing friendships with other mythical forest dwellers in her kind impulsiveness. Nonetheless, some parents in Russia continue to use unfavorable image of Baba Yaga as a threat at bedtime.
