Cockerel and the Sun (1974)

As you know, the rooster, waking up early in the morning, cannot restrain himself from wanting to tell everyone around that this has happened, therefore he wakes everyone up with a loud cry. So begins a new day. And it doesn't matter if it's a village or a small town, however, people have always focused on the wake-up signal given by their own bird. People, but not the sun, which pleases us with its warm rays. A donkey, a bear and a kitten have always thought about who gives the signal to the hot star, who should get up before everyone else? What will happen if the sun sleeps and does not come out into the sky?
