this picture is from the episode "Party of One"
in fact, judging Pinkamena on "Cupcakes" alone is a pretty dumb move.
It's a fanfic m8, and just because you judged it by comparing it to Twilight doesn't make it seem any worse or any better. You're just wasting your typing time by trying to make a point on a circle where it's impossible to add a point of tangence on.
So am I. Your comment is well over a year old.
