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.

Nu pogodi!

The first episode of Nu pogodi! (originally "Ну погоди!" and in translation You just wait!). The series of these animated shorts began in 1969 and became enormously popular in the Soviet Union and the countries of Eastern Europe. These cartoons are almost wordless, albeit full of grunting, laughing, singing, waltzing and such. It is, however, the trademark of the series that at the end of each episode the Wolf, having failed to catch (read: eat) the Hare, will utter the fatal words announcing how inevitable the next encounter is:
"Just you wait, Hare!"
Nu pogodi!
An Eastern variation of Tom and Jerry?
Perhaps, insofar as Tom is a hooligan that abuses the minors, breaks the laws, drinks, smokes, plays the guitar and rides a motorbike.
