''Two Worlds; One Family'' is a ''WesternAnimation/MyLittlePonyFriendshipIsMagic'' fanfic written by WebVideo/TheMysteriousMrEnter, which can be read [[http://www.fimfiction.net/story/94839/two-worlds-one-family here]]:

It was late on a winter's night when Fluttershy found a strange creature nestled in a basket on her doorstep. This creature looked like some sort of hairless ape, which eventually turns out to be a human. Fluttershy takes the poor infant inside, and names him Harry—hoping that that name would keep him warm. She tries to raise him as just another one of her animal friends, but he acts so much more equine than any of her other animal friends. Then one day, Harry starts talking, and calling Fluttershy "mama." From that day on, she decides to raise Harry as her own—to the mixed reactions of both her friends and the other citizens of Ponyville.
