Ponies crossed with my favourite film. If you don't know what this is, it's a ponified scene from Children of Men. If you have seen the film you'll probably notice I've left out something from this scene. I left it out because I didn't want to have to put a mature rating on this or at least wanted it to be fine for all ages.
I was going to use a Zebra as that would fit the movie better but then realised it had to be contained within a single species for it to really work. So I chose Derpy.
By the way, someone should make a cross over fic of this story.
