How did the Lion Cub and the Turtle sing the song? Yes, that’s how they sang, as the writer Sergei Kozlov taught them. At first they sang in the book, and then they moved to the cartoon. Where did the cartoon about the Hedgehog in the Fog come from? Also from the fairy tales of Sergei Kozlov. So his Hedgehog wandered in the fog, wandered, and it turned out to be the best cartoon in the world. Such tales are written by Sergei Kozlov. And about Tilimilitryamdia - he too, but he has a lot of fairy tales. And everything is in this book. And all ends well.
