Susan and John are excited when they learn that FR Peregrineโs Travelling Fair is coming to Scatterbrook for one night only. But as much as heโd love to join his friends, Worzel canโt be seen wandering around by humans. He recalls the legend of a fairground with an enchanted organ. It is believed that, with the right music, the organ has the power to send humans to sleep so that scarecrows can enjoy the rides without the fear of being seen.
