Hugtight glue plays an important role in the second half of The Twits. The glue is described as the strongest glue in the world, and it is introduced as the way the Twits capture birds to bake in their weekly pies. In this way, the glue represents the Twits’ cruelty and their disregard for any living creatures other than themselves. The glue also represents the unmovable personalities of the Twits. Their years of being terrible have acted as the strongest glue, keeping them firmly fixed in place, and they are unable to grow, change, or learn.

In the book’s final chapters, the Hugtight glue represents how our own negative actions come back to haunt us. For years, the Twits have used the glue to capture birds in a particularly inhumane way. After watching this injustice for a long time, the monkeys are angry at how the Twits treat the birds, and thus, Muggle-Wump doesn’t hesitate to use the glue to trick and ultimately defeat the Twits. When the Twits return from buying guns, they find their house turned upside down. They panic, which keeps them from thinking clearly and realizing that they own a glue powerful enough to stick all their belongings to the ceiling.
