Bluff

Bluffs are a large herbivorous quadrupedal animal, that are often seen grazing in grassland habitats. They are made distinctive by their two different sets of feet. The softer padded front feet, used to cushion the Bluff's heavy body in rocky terrain (almost like a natural gel-cushioned shoe) & their gripper, harder rear feet that are used to help in slippery, muddy terrain around rivers & deltas.

History
The evolutionary roots of Bluffs aren't known. But historically, early civilizations would use Bluff for a variety of reasons. Including their pale-yellow milk, leather, and in winter for their fatty layer under their skin. There are even archaeological records of arrowheads, tools & spear-tips made out of the Bluff's hard toes on their rear feet. But in modern times, they aren't needed for much of anything in developed civilizations anymore & are left alone. With the only exception being sometimes used as zoo animals for their odd appearance & large size.

Abilities/Personality
As wild animals, Bluffs don't seem to have much of individual personalities, but they are peaceful & almost always avoid conflict. They can run decently fast for their size, but it's rarely ever fast enough to out run a predator, leaving Bluffs no choice but to try and use their large size & hard rear foot to kick predators away.
