Where does the trembling from fear come from? How does the internet actually work? And which pet has the best sense of smell? Checker Tobi poses the questions that interest children. Together with his cheeky robot assistant Roberta, he takes his fans on exciting adventures and meets many experts to find the answers. We learn, among other things, what the basic emotions are, how mobile phones connect to the network, what the immune system is, and why forests are important for our climate. He also checks whether one can learn the language of animals and what rights children have in Germany.
