Wolpertinger

It's rabbitdeereagle...half rabbit, half deer, half eagle.

The Wolpertinger (Crisensus bavaricus) (also called "Wolperdinger", "Poontinger" or "Woiperdinger") is a fictional animal said to inhabit the alpine forests of Bavaria in Germany. It has a body comprised from various animal parts – generally wings, antlers, and fangs, all attached to the body of a small mammal. The most widespread description is that of a horned rabbit or a horned squirrel.

The Wolpertinger is not a typical cryptid, as local people likely never believed in its existence. Rather, it is some kind of traditional prank belief, as is evident from the many stuffed Wolpertingers displayed in village inns along with real hunting trophies, which have been fabricated deliberately in order to make fun of gullible foreigners who may want to go hunting for this remarkable animal.

Like the Jackalope, the Wolpertinger is thought to have been inspired by sightings of wild rabbits infected with the Shope papilloma virus, which causes the growth of antler-like tumors in various places on the rabbit's head and body.

A strikingly similar creature called the "rabbit-bird" was described by Pliny the Elder in Natural History. This creature had the body of a bird with a rabbit's head and was said to have inhabited the Alps. Its similar description and range are probably merely a coincidence.
