Outdoor Theatre: The Twits by Roald Dahl

Mr and Mrs Twit never wash, and they live in a smelly old caravan. Bored of playing cruel tricks on each other, they decide to open a circus. They capture a family of monkeys and brutally train them to perform in the ring. The local birds try to help by tricking the Twits into believing the world has turned upside down and dropping glue into their hair. Only when the Twits have met a sticky end, and only if the audience plays its part, can the monkeys finally be released.
Illyria promises a slimily, stickily, revoltingly funny show, from the most popular children's author in the world.
