The book tells the story of the giant monster Shlopster-Klopster who stole the Moon and of the little boys of different nationalities for whom it proved difficult to muster enough courage to confront him. It is only the smallest and most ordinary among them who managed that. It turns out that the monster was only scary only as long as children were afraid of him.
