Kolobok is a traditional Russian folktale character who is a small round ball of dough that comes to life and rolls away from its creator. As the kolobok rolls through the forest, it encounters various animals who try to catch and eat it, but it outwits them with its clever tricks. Eventually, the kolobok is swallowed by a sly fox who tricks it into jumping into its mouth. The story teaches a moral lesson about the consequences of being too trusting and impulsive.
