Mr Twit is a foul and smelly man with bits of cornflake and sardine in his beard. Mrs Twit is a horrible old hag with a glass eye. Together they make the nastiest couple you could ever hope not to meet. Down in their garden, the ghastly, evil Twits keep Muggle-Wump the monkey and his family locked in a cage. But not for much longer! Because the monkeys are planning to trick the terrible Twits and make their escape, once and for all.
