Rainbow Dash flies east.

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

Spike led Thorax into the throne room of the Crystal Castle confident he could convince the others that the changeling could be trusted. That he meant no harm, and instead wanted to be an ally and live peacefully with them. That he could make them see Thorax for what he really was. That they could befriend the changeling and accept him as one of their own.

They didn't.

And consequences followed.

The perfect bioweapon: takes effect within minutes of exposure, has a 100% success rate, and those exposed spread it wherever they go. Armed with this powerful new weapon, an evil organization attempts to bring about a reign of terror unlike any seen in the world before. Unfortunately, the perfect weapon doesn't work quite as intended. Instead of killing its victims, it changes them into ponies.

Tiny, adorable ponies.

The world is doomed.

This story was written for the Transformations group story contest. It was originally published under the name "Consequences," though this story has been heavily revised since then.

Thanks to my usual crew Two Bit and Sparktail for the editing, and for everyone who submitted feedback on the original contest entry. As usual, my coverart is by the fantastic Zutcha, so go ahead and check him out of you haven't already! The story's changed a great deal since then, hopefully for the better.

Dear Celestia,

If you're reading this it means my infiltrators are better than your guards. Boom! Point to Chrysalis. But seriously, don't take it too hard. Changelings are just naturally better than ponies at so many things. That being true, wouldn't it be a lot easier to work with us instead of against us? Don't worry, I'm not talking about another coup. I'm talking about a real partnership, an opportunity that you just can't afford to pass up.
