Description from the source:

The last corrupted element of harmony floats along in search of it's unfortunate bearer. It has taken longer to find the pink pony then any of the others, but it should be quite easy to convert her. She is already quite bubbly and airheaded, all she will need is a few modifications.

There! At last, the element hones in on it's prey, bouncing happily down the road, blissfully unaware of her encroaching fate.

"Oooh what's that?" The pink pony asks as the necklace floa- "No silly, not the necklace! I spotted that a while ago. I mean the text boxes!"

wh- what?

"Yeah! All the floaty boxes in the air filled with text! Oh! Am I in a comic? Oooooh does that mean this is the description? I've always wanted to be in a description!"

What are you even... why is the dialog different down here than it is up there?

"Because I'm not in the description up there silly!!!"

Wha- Stop climbing out of the panels! You're going to break the dimensional barrier!

"Ah don't be such a spoil-sport! It's cramped in these things anyway!"

Desperately, the narrator does the only thing it can think of to stop her! Both in the text and the comic above, the cursed necklace swoops in, and CLOSES AROUND HER NECK!!!

"Hurk?!"

Whew... that was close. Having been dragged back into the confines of her comic panels, the curse's corruptive magic begins to seep into Pinkie Pie at last. As is subtly begins to alter her body, it takes on the much more important task of neutralizing her reality magic. The first thing the curse takes is her ability to break the fourth w-"What are you talking about silly? Are we playing pretend?"

Sigh. Of all the irritating... OK, fine. We're playing pretend.

"Oh yay! Can I pretend to be a pirate? I'm thinking a lot about booty all of a sudden! (why do I feel so jiggly?)"

All right. But Pinkie, if we're going to play pretend, then I have some rules. This won't be any fun if we don't follow the rules of the game.

"All right! What are they?"

You have to do everything I say, and Everything I say will come true.

~~~"OK!!!" ~~~

Heh. Foolishly, the Pink menace gives a binding verbal concession to the curse's terms. The magic manifests as a glowing pink bubble as the agreement is pulled from her darkening lips. She is doomed now.

"Huh? What was that? What are you talking about?"

You WILL do everything I say now Pinkamina Diane Pie. And I say that you will STOP BEING SO CHEARFULL!!!

POP!!!!! With a sudden burst, the pink pony's hair deflates. Her body is firmly in the magic's hold now, beginning to change and darken as her colors dull.

"What... Did you do? I feel, so wierd... You're so mean... I don't like this game!"

Still interfering. Hmpf. Well fix that. Pinkie! You will become TO DUMB TO READ!!!

"hhuuung... Hu? Wha?" The changing mare's eyes suddenly go blank, as she struggles to understand what had been clear a moment before. The sudden rush of magic that had been her intelligence drains from her head with dizzying speed, and begins to fuel the growth of her hips and chest. Small tendrils of magic form into piercings and black jewelry.

"Whha, happened? I can't understand the word thingies? Why are the boxies turning pink?"

Uhg. Ok. And you can no longer break or see the fourth wall.

"Oooh... What was I just doin? I can'... remember..."

Finally free of distractions, the curse finishes up it's work. Pierced nipples crown bouncy, voluptuous breast that were once brain mater, fishnet stockings form over cloven hooves, and the curse settles into permanence. The last element of harmony has fallen. There is no hope for equestria now.

... or, is there? The curse's spread is certainly causing... chaos. If Empress Cadence want's to retain her hold on the land, she might have another threat to deal with.

Whew! Aw man that was close! Pinkie almost escaped into the real world! Who knows what would have happened if the curse had come with her. We might all have been doomed!

Still working on commissions, but I've been doing little bits of this in the background the whole time. I do have some ideas for other characters in this series, but we'll see. For now, I have a few other things I'd like to make.
