The Duffers were a large clan of about fifty dwarfs, who have the distinction of all later being transformed into dufflepuds, a new dwarf monopod sub-species. Originally normal, two-legged dwarfs, the Duffer family lived on Coriakin's Island under the employment of the magician Coriakin. When they collectively refused to carry out some unknown task for Coriakin, however, he angrily transformed their two legs into one. The only known name of any of the Duffers was "Clipsie", the Chief Duffer's daughter.
