Kachanov made numerous films for children. He started with puppet animation such as A Little Frog Is looking for His Father, The Mitten and, most famously, the Cheburashka series that turned Cheburashka into one of the iconic characters of Soyuzmultfilm. In his late years he switched to traditional animation with the feature science fiction film The Mystery of the Third Planet (1981). Adventures of Mowgli mini-series by Roman Davydov was released from 1967 to 1971. Just like Winnie-the-Pooh, it was not conceived as a reaction to the Disney's The Jungle Book (even the first episode was developed simultaneously) and followed the original plot closely, appearing more adult and spiritually closer to the book. In 1973, the shorts were combined into a 96-minute feature. The rising popularity of the industry started drawing people from other areas. Vasily Livanov, originally an actor, finished animation courses and directed several experimental pictures. Yet his biggest success was The Bremen Town Musicians (1969), an animated musical film heavily influenced by rock and roll and hippie cultures. The first part was directed by Inessa Kovalevskaya who also abandoned her position at Goskino to work on animated musicals. After she left the project, Livanov directed the sequel by himself. The three main characters were voiced by the leading Soviet pop singer Muslim Magomayev. 1969 saw the birth of Russia's most popular animation series Well, Just You Wait! directed by Vyacheslav Kotyonochkin. These seemingly simple miniatures about a wolf chasing a hare through Soviet-style cartoon worlds owe a great deal of their popularity to the quality animation, varied soundtrack and cunning subtexts built into their parts. The original series ran from 1969 to 1993. During the mid-2000s, an unsuccessful attempt to reboot the series was made. Also, in 1969, a long-running animated anthology series Happy Merry-Go-Round was founded by Anatoly Petrov and Galina Barinova. Each episode combined several short experimental films by the beginning directors like Leonid Nosyrev, , Eduard Nazarov, Gennady Sokolsky, Garri Bardin and . Most of them gained acclaim later on, working in their own unique niches. Anatoly Petrov showed extreme realism (close to photorealism) without rotoscopy, photography or any "cheating". His style was known as "photographics", or "graphical painting"; for many years he developed the so-called effect of moving glaze in a 3D environment using traditional animation materials. The final result was close to advanced CGI long before it was invented. Among his best
