Herpis-Derpis 

A mutate of the Succubus and Harpy. A not so endangered species that is mate-hungry, and it's mating call is "Wanna F**k?" or "Got any Drugs?". The Herpis Derpis Maximus has a high rate of vaginal and anal infections. These infections can spread via mating and there goal is to infect anyone and everyone in the world. You can tell the animal is weak when it rubs its nose and sniffles a lot. They travel in flocks. The rate of spreading the infections is a pandemic indeed.

The Herpis-Derpis was seen capturing verginities behind a dumpster.
