I personally never saw it, but my friend and I agree that it feels more like some fan's concept for an episode that ended up getting made real than an actual legit plot or a story the creators came up with themselves. (Heck, the artstyle came from users on DeviantArt iirc).

I also know it's pretty controversial among the community, with some liking it, some hating it, and some liking the concept but not the execution (like me). So I figured I'd ask the sub to see what people here think about it.

(Sure, it's taking it a bit out of context, but I think it's still neat)
