A sweet and well-done children's film about how one can make friends even far away from home. It also shows a little of various parts of the world and what polar explorers do. It's quite pretty to look at. This is cutout animation, but animated in such a smooth way that you can barely tell. E.g. to animate talking, the head is replaced with each frame, so that it looks very smooth. This way, they could use each type of animation ("moving existing shapes" or "redrawing") for the types of movement that it is best suited for.

They do something similar in many American stop-motion puppet movies today, by 3D-printing many different heads and replacing the character's head for each frame, so that it ends up looking like CGI (e.g. in "Corpse Bride" or "Coraline"). In this case, it looks like a children's illustrated story book come to life. They also used this type of mixed cutout-cel animation at Ekran studio in those years, but seemingly not so much at Soyuzmultfilm.
