I've long since suspected something weird was going on with my ponies. They let their hair grow long and started listening to loud music in the middle of the night. Sometimes I'd see them hastily hiding metal objects in their stalls which I later discovered were ritual knives and pentagrams. But it all came to a head tonight. At first everything seemed normal. Then suddenly... the demons hit! They eventually started trying to gnaw off each other's legs while chanting in some ancient language. The whole experience was very mentally scarring for everyone involved. I'll never forget the looks of pure hatred in their possessed eyes, or the venom on their dripping white fangs. Fortunately, I was able to get an exorcist to come out on short notice, and they're back to normal now.
