ROB 344-66/IIIa, called Robbi, is in the third grade at robot school. Every year there is a big robot test. This time, Robbi has been given the practical task of recreating an invention. To do this, he secretly photographed the construction plans for Tobbi's Fliewatüüt at night. The inventor Tobias Findteisen, called Tobbi, is in the third grade of elementary school. His invention can fly like a helicopter (Flie), float on water (wa) and also drive like a car (tüüt). The vehicle is powered by raspberry juice from the cellar. One night, Robbi visits the inventor Tobbi to show him the Fliewatüüt, but above all to ask him for help in solving the difficult theoretical robot examination task, as he can use the help of a human child for this. So the two set off together in Tobbi's invention, which takes them all the way to the North Pole and Scotland.
