The Most (Un) Boring School in the World: Duel of the Schools (vol. 5)

Often, school’s just not exciting enough and there are too many rules. No matter where the series is read, kids can identify with the stories and their main theme of pranking and tricking teachers and schoolmates. Max's class is competing against another school. But if they lose, the next holidays are threatened with cancellation! Luckily, Inspector Rumpus keeps an eye on the children - and helps them in time in dicey situations.
