The Mineral Springs Campgrounds. They have long been considered by pony kind to be a natural wonder that evokes feelings of awe, beauty, tranquility, and the faint taste of salt in one's mouth. But for three fillies, this charming spring evokes another feeling all together...TERROR!
IT CAME FROM BEYOND THE STARS, TO DO...uh...STUFF!
NO PONY KNOWS WHAT IT IS! NOT EVEN ME!
Prepare for a (kinda) THRILLING tale that will leave you QUAKING with FEAR! (It won't.)
Can you face the HORROR that is...THE SLUG-MAN OF MINERAL SPRINGS?! (Yeah, you can.)

I think this description is better than the actual story.
