One day, Fluttershy finds a strange creature in the Everfree Forest, an animal that's half-pony, half... something else. Soon, all sorts of weird creatures are popping up in Ponyville, leading to strange, sexy situations with Twilight and her friends. But why are they appearing now? What could have driven them out of hiding? What mysterious forces are at work here, and how will Twilight and her friends stop it?

This story involves creatures from SirachaNotSauce's blog:Monster Mare Encyclopedia (monstermareencyclopedia.tumblr.com). It's not necessary to read that before you read this (in fact, I would recommend reading it after you read this), but it is quite good. These creatures are her creations - I'm just using them because I think they're a lot of fun to write about.

If you have a particular monster mare or pairing you would like to see, leave a comment and I'll consider it! Thanks for reading.
