I noticed on a hit from the Ponychan board, so I went to check it out. The guy who made the clip for the Dizzy Pie video mentioned that he'd like to also see the other sister dancing, so... here we go!

I named her Dancie Pie, because... well, why not? :P
(Actually, it looks like the fanbase has decided on "Inky Pie", but I don't feel like changing my video :P)
Song is Sandstorm by Darude (which is a fantastic song, if incredibly overused in videos).

So, BronieBrown, if you happen to see this... enjoy!
