The carnivorous Jackalope hails from North America, where it creates mischief and mayhem in trickster style. It has the body of a jackrabbit and the horns of an antelope -- hence its name.
The Wolpertinger is the Jackalope's Bavarian cousin, of sorts: along with antlers, it also has wings and fangs, and its body, although usually a rabbit's, can take the form of any small mammal.
