How I Found My Friend (1981)

In the distant primitive world, where our ancestors lived - primitive people, amazing flowers bloomed, amazing animals walked and these events take place. Two little primitive people, two children, with all their curiosity explore the new world, observing the wild chickens that inhabit it, rhinoceroses with trees instead of horns and many other equally interesting and amazing creatures. One day, while playing hide and seek, they meet a cute puppy on their way, who will become their faithful friend and brave defender.
