When Mr. Twit wants to take revenge on Mrs. Twit for the worms in his spaghetti, he devises a particularly clever and devious ploy. Mr. Twit is a repulsive and unsavory man who always has remnants of cornflakes and sardines in his beard. Mrs. Twit, on the other hand, is cunning and crafty, constantly looking for the next nasty trick to tease her husband with. The Twits are so repulsive and evil that they even imprison Muggle-Wump the monkey and his family in their garden.
