The character Ded Moroz (Grandfather Frost) needs explaining first. He's sort of a Russian Santa Claus (not exactly the same thing). Anyone learning Russian is likely to hear about him during first year studies. That said, Valentin Karavaev's "Ded Moroz i leto" ("Ded Moroz and Summer" in English) is an OK cartoon. It basically depicts the Russian Santa spending his days packing presents for children in his wintry landscape, but then he wonders what summer is like. Turns out that summer is not something that he can handle. I guess that people should stick to their settings. Other Soviet cartoons were more interesting than this one (you gotta love their version of Winnie the Pooh), so don't make this your first choice.
