"Kolobok" is a Russian folk tale.

Once upon a time there was an old man With an old woman. The old man asked the old woman to bake him a Kolobok (a dough bun). The old woman baked a wonderful pink Kolobok and put it on the window. Kolobok tired of lying on the window, he jumped up and ran away. 

Rolled down the path straight into the forest. In the forest he met a rabbit who said: "Kolobok, Kolobok, I'll eat you!"

"Don't eat me, I'll sing you a song" - replied Kolobok, sang a song and ran away. 

On the way he saw the gray wolf and the bear. They also wanted to eat a Kolobok, but he sang a merry song and ran away. 

But the Kolobok met a cunning Fox. He also sang her his song. She praised the Kolobok, but said it was bad to hear. The Fox asked him to sit on her tongue and sing her wonderful song again. Happy gingerbread man jumped on the Fox language. And a sly Fox swallowed it. 

Yum, and there is no Kolobok!
