The Diary of Petya Vasin and Vasya Petin (Dnevnik Peti Vasina)

This is the story of two cheerful and witty friends and their parents, whom they closely resemble. Vasya and Petya are tireless explorers, so they can't go a single day without adventure: they uncover a criminal's insidious plan, organize a painting contest in an apartment, or hunt for treasure.
