This is a story about a little hedgehog (voice of Mariya Vinogradova) and his friend bear cub (voice of Vyacheslav Nevinniy). They would meet every evening to drink tea, count the stars and have conversations. One day, as usual, the hedgehog decided to bring raspberry marmelade. As he went to the bear to count the stars, he was already thinking what to talk about. While passing through the woods on the way to his friend, the hedgehog finds a horse standing in a fog. He is curious as to whether the horse would suffocate if it lay down in the fog. Being an explorer, the hedgehog decides to explore the fog.
