Featured in Matilda the Chokey is a very tall but narrow cupboard that is 10 inches square so no one can sit ,squat in it. It closely resembles an iron maiden. The Chokey is filled with broken glass sticking out in the walls with nails on the door and whoever wobbles will either be spiked by the glass or the nails. Miss Trunchbull uses this whenever the children break the rules and one of the victims is Hortensia, a girl who plays some tricks on the Trunchbull and she gets caught in the end. Sometimes kids are kept in there all day. In the movie Miss Trunchbull puts Matilda in the Chokey on the latters fathers behalf for selling her a defective car.
