Each episode tells an adventure of the main character, Gustav, related to the grey realities of urban life.
Characteristic feature of the show was that episodes were independent: for example, Gustav is sometimes a bachelor, sometimes has large family.
In Eastern Europe and Yugoslavia the episodes were broadcast on TV in the 80s, usually as airtime filler.
The series was also broadcast in Western Europe and even in New Zealand - because it was not using language, other than gibberish sound, it was able to easily transcend boundaries.
Trio of well respected and award-winning authors, Dargay-Nepp-Jankovics, was responsible for the development of the quirky show.
