This creature evolved from an aquatic ancestor uses the tail as a third leg, since it only had two flippers like dolphins, and they became jointed over time, growing hooves to cope with their sandy environment. Each of this alien's four eyes has a goat-like pupil, ready to spot danger and call to the herd. They are omnivores, like pigs, and eat just about anything. Including bark, berries, carrion, and smaller creatures.
No poseable vector yet :( Here is the first creature I done. Space for a call.
