Čumidlo a fujtajblíci s hradním tajemstvím – Klimek Hynek (2019)

The Čumidlo is a little ghost that looks like a small dragon with big eyes. It appears when someone is doing something they shouldn't. It then stares at them intently, just watching... The Čumidlo has settled in a guesthouse in Šumava, where students often go for nature school. Just there, mischievous fifth-graders from Prague have arrived, and so the Čumidlo, along with its helpers, has its hands full. Will they manage to tame the class of rascals? With another class, the Čumidlo will visit Kašperk Castle and try to find out about the local ghosts and why none of them have encountered any yet.
