Timo and Hanna are best friends. But sometimes they argue. When Timo simply takes Hanna's doll stroller away, she has had enough. Out of sheer anger, Hanna bites him. She bites Timo on the arm as hard as she can. But is that okay? No! Because only the crocodile is allowed to bite! Can she scratch him instead? No, only the tiger is allowed to scratch. But what do children do? Clever children talk to each other!

With the help of this humorously illustrated story, children learn playfully not to take their anger out on others, but to solve their problems by talking to one another. An important book for children aged three to six years.
