Hedgehog in the Fog

A beautiful 1975 animation by Yuri Norstein.
I recently saw it for the first time and it just blew me away.

Hedgehog and his friend bear cub have a nightly ritual where they drink tea, count the stars and have conversations. On his way to bear cub's house, hedgehog sees a white horse, and wonders whether she will choke if she lies down in the fog. He decides to investigate and delves into the fog, becoming hopelessly lost.

can it get much better than this?
yes! watch it!
