A dark operetta for curious children and their grown ups. Have you ever done things your parents told you not to do? Have you swallowed the pips of an apple and waited for a tree to grow in your belly? Have you made a face when the wind changed? Or turned your back on the sea? In Bobby Rogers' town everyone lives very normal lives. But Bobby has noticed that a child who was there one minute is gone the next. So he digs a hole through the earth, all the way to kangaroos and upsidedownness. and he may have stayed forever there, but vanishing kids does not seem fair, and there is nothing so fun as a grudge to bear, so one day Bobby Rogers returns to Upper Crumble to settle the score.
