La Linea

Do you know this animated character?

Its name is La Linea, and it's a character created in 1969 by Osvaldo Cavandoli and dubbed by Carlo Bonomi. At the beginning it had been created to some ads. Finally it became an animation character known by many people, but not many know their language.

I have read in many forums and videos, discussions about its language. English? French? Italian? Hungarian? Spanish? And invented language? It isn't any of those posibilities.

It is a language that I really know, because the mistery and forgotten language is Milan's language :)
