Another possible image for Shadows of Giants, in which a human Fluttershy appears on Earth.
Even though you don’t see anything in the image, I am labeling this with mature content as a precaution. I think it is tasteful, but I have no way of knowing if anyone else will agree with me. You’ll have to tell me what you think.
No, I am not one of those Bronies. The prompt for the story said Fluttershy is found naked, and if her state of undress had to be specified she must be human, so that is what I drew.
