Ducoboo is always sitting a the back of the classroom and getting in trouble. He has to employ treasures of imagination to avoid getting interrogated by the teacher and having to wear the dunce cap. In his efforts to be 'a good student', he copies relentlessy on Leonie, who sits next to him and is an ace student. However, she hates people copying her work and Ducoboo ends up having to stand in the corner more than once.
