The eurka is a female of the homosapian species that resides in he southern regions of the United States. Primarily between Kentucky and Florida. The Eurka is one of the few mammals that will breed outside of its own species and perfers the rare "Hadd Ladd". Like the black widdow spider, the Eurka's mate does not live long after the mating ritual is complete because the Eurka's previous mate, the "Kentucky Dumbass" tracks down the Hadd Ladd to kill and eat his remains. The Hadd Ladd and the Eurka pair up as the Eurka migrates south to Florida in the summer time.
