Anyone who knows Kuschel knows that this cat is always right. Really always! That's why it's clear that the yellow thing in the treetops is a frog. Since his feline friends doubt this, Kuschel searches the internet and comes across a yellow, very poisonous frog. To prove his point, he wants to print the page, but unfortunately, it works too well: 31 copies fly out of the printer and scatter - thanks to a gust of wind (or not) - all over the city. Panic breaks out. Children and cats are no longer allowed on the streets, and frog experts are called in. Kuschel feels quite uneasy because he has now realized that the frog is actually something completely harmless. Axel Scheffler has once again brilliantly portrayed Kuschel in all his arrogance.
