'A true genius . . . Roald Dahl is my hero' - David Walliams
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.
