This is a story of a man that takes 3 ponies that shouldn't be. Who are they? How did they get there? Will they get home? and what will he do?

This is a story that is an idea that I had and that I just couldn't let waste. Writing is not my strong suite so any advise is appreciated.

Note: there is zombies… and this will end up in Equestria. The Gore and Sex tags will come in later chapters.
