At the end of Roald Dahl's book "The Twits" is that on the day of the arrival of the Roly-Poly Bird from Africa shows the monkeys and the surviving birds how to get the revenge they have craved for years. They glue the carpet and furniture to the living room ceiling while the Twits are out. On the Twits' return, two ravens swoop over and drop glue from paintbrushes held in their claws onto the Twits' heads. When the Twits go indoors and see their furniture upside down, they stand on their heads, believing they are upside down, and because of the glue on their heads, they remain stuck that way. With the Twits out of the way, the Muggle-Wumps are able to return to their native Africa with the help of the Roly-Poly Bird. Eventually, the Twits' bodies collapse into themselves, until there is nothing left of them but their clothes.
