"Mountain of Gems" is the largest project in the history of Russian animation. It was created according to the fairy tales of the peoples of Russia by the Pilot studio under the direction of Alexander Tatarsky by the best modern animators. There are also series of cartoons designed in the same style (plasticine "Peoples of Russia"), and individual author's short films. All of them are very different and unlike anything else, well drawn and with excellent voice acting. Click on the link - it will take you to youtube. Just be careful: you can "hang" for a long time, switching from one cartoon to another!
