Each 30 minute episode is dedicated to a separate issue or theme and consists mainly of related short featurettes, which explain, explore and educate how things of everyday life and even complex systems work.
Its central character (Peter Lustig as himself; later Guido Hammesfahr as 'Fritz Fuchs') is a handy and technophile middle-aged man with childlike curiosity, seeking an eco-friendly and self-sustaining lifestyle.
Early in the series he moves from his city house to the outskirts of "Bärstadt" and into a blue caravan, which has become the shows landmark and a stable part of German popular culture.
The wardrobe is being transformed into an outside toilet room including a water flushing system and a glass cabinet is added to the cabin wall as a bay window.
He is lazy, eats mostly unhealthy food like pizza and burgers, doesn't do any sports, has no interest in a more environmentally friendly lifestyle and often mocks Peter's idea.
The show's title sequence focuses on the flower's strengths as well, while one of Lustig's main messages to children was "there's no such thing as weeds", inviting them to see nature's vigorous beauty in all its lavish glory.
These include his dog Keks (Cookie), his female friend Yasemin (Sanam Afrashteh) and the strict code enforcement officer Heinz Kluthe (Holger Handtke).
