Now, before I did this, I didn't know (or bothered to find out) that the ponified caricature of this particular "unexpected guest" from Scare Master was a reference to an actual anime, or that she was a girl (oh, c'mon).
Oh well. We all'd like to spend quality time with our favourite animated characters, don't we?
