The Twits is one of Roald Dahl’s most popular children’s books. Roald Dahl’s The Twits tells the tale of a pair of horrible twits and the tricks they like to play on each other. Mr and Mrs Twit are the smelliest, ugliest people in the world. They hate everything — except playing mean jokes on each other, catching innocent birds to put in their Bird Pies, and making their caged monkeys, the Muggle- Wumps, stand on their heads all day. But the Muggle- Wumps have had enough. They don’t just want out, they want revenge.
