The bartender pulled out a map that revealed what looked like only the lower half of the United States which revealed 25 states, where you knew have had a bunch of western towns. The state you were in, was Texas, where you've seen multiple horses, and cows ride out into the fields, while they search for food.
"The town where that creature came from was known as "Hoof Hollow"," the bartender explains. "Many people from inside, and outside of Open Gulch see shadows of these centaurs, and cowtaurs from the looks of it, as they have revealed to have the ability to escape more times after we humans look away. Whatever you do listen to my warning, and do not go to Hoof Hollow, or you'll end up just like the few sorry saps that have lost their humanity after entering that town, and never return to normal.
