Dr. Splattenburgers isn't actually the name of the story, it's the name of the author. He wrote three stories during his time on FanFiction.net, each more bizarre than the last. And with titles like Avatar: Redemption in space, Portal 3 GLaDOS and the death puzzle part 1 with no part 2, and Hitler in Equestria, it's pretty much exactly what you'd expect.
