An indiginous worm located in South Africa. They hang from trees and when approached they make strange wooping noises and jump at your face. Then they suck the sweet sweet juices from your eyes and make a nest in your intestines. They can grow from 5 inches to 5 feet long. The doppel-ganger is endangered so please do not hunt them for sport.
