Cheburashka

This is the first episode of Cheburashka (in English: Topple), an unforgettable and beloved Soviet cartoon (1969).
For the last few seconds that end the first episode (and which are certainly worth the extra effort) press here.
Cheburashka wakes up in a crate of oranges in Russia. Feeling lonely, Cheburashka answers a personal add and befriends a crocodile Gena, who works in the zoo as the crocodile.
