The offspring of a Graves and a Katie. These creatures are part Cro-Magnon and Walrus-Whale, and are hermaphrodites. At conception, the Gratie weighs approximately 200 - 215 pounds and stands between 67 to 77 inches tall. With drool commonly hanging from the side of their mouth, they closely resemble the physical traits of the mother with the mental capacity of the father. It has teeth akin to that of a hyena, with a walrus shaped head and very large ears.
I could tell by the recessed eyes and the protruding forehead, combined with the pigtails and complete lack of intelligence, that this creature was in fact a Gratie.
