Zippelzefix - what a great read-aloud by Alex Rühle and Axel Scheffler! Zippel is a little castle ghost. But who actually said that castle ghosts live in castles? No, Zippel lives with Paul and his parents - in the door lock of their old flat. The day after the summer holidays, Paul discovers him there, and so the funniest time of his life begins. For Zippel is still a very young castle ghost and is always up to nonsense. Things get so exciting with Zippel that Paul can no longer imagine life without him and he takes his new little friend firmly to his heart. But then the door lock is to be replaced - and Zippel's home is suddenly in danger.
