Fluffy Pony RPG: Tales of Sh*t and Skettis is a (very) niche, tongue in cheek, black humor RPG about sentient equine biotoys (adult content warning).
You are a fluffy pony.
No,really. You are a brightly colored biotoy with a more than passing ressemblance to a (very) small horse. And a guinea pig. And also a shit factory. You can talk (with a lisp), have a (very) limited grasp of the basic concepts of existence (life, death, love, good, evil, shit, that kind of thing), and an even more limited intelligence. Some say you are nothing more than a preprogrammed biological machine, not really sentient. Others consider you real animals (albeit a little annoying); living, sentient beings with feelings, hopes and aspirations. It all depends on your headcanon.
