When Discord revealed the Blue Flu to be a big fib, everypony thought that that was water under the bridge. Little did they know that he needed the tea for another reason. To turn Princess Celestia's life upside down. The princess has been made into a Tatzlpony, and now it's her duty to not only hide it from her ponies at large to avoid mass panic, but to try and learn to live with her new habits and urges. Will she ever be the same? Will her ponies ever quit being so specist? Will Discord get whats coming to him? Who knows!

When Twilight's latest spell goes predictably awry, she ends up swapping bodies with all three of the Cutie Mark Crusaders. At the same time.

Written for the Body Swap Writing Contest

True, heart-stopping terror takes many forms:

Foul beasts roaming the dark who consume their victims, flesh and soul.
The object of one's affections finding a diary they weren't meant to.
Being tardy.

But until now, Equestria has not known the meaning of fear. The past's petty concerns and phobias mean nothing this day, for today, Equestria shall experience unimaginable horror. Today, Pinkie Pie becomes a unicorn.

This story is a sequel to A Stitch in Time

Having discovered the message left for her by Star Swirl the Bearded in the distant past, Twilight once again finds herself caught up in the middle of a struggle against forces far greater than herself. In order to even stand a chance she'll need to travel further and wider than she ever has, and forge some unlikely alliances with old enemies. All to bring down the powers that have manipulated and shaped her entire life, and retake control of her own future.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

When the Cutie Mark Crusaders dig up an ancient magical artifact, they unleash a spell on the town that allows everypony to see a "lie meter" floating above each other's heads. While attempting to solve the mystery, Twilight Sparkle has to analyze the tenuous balance between friendship and honesty. She doesn't like what she finds.

Princess Twilight Sparkle lay there in anguished silence for almost a minute until she decided to let Scootaloo, Apple Bloom, and me help her. It came out as a whisper: "My special talent isn't magic." Of all the ponies we might help, I had never imagined our first might be Twilight, or that it would essential for Equestria that we got it right.

Thank you everypony!

This is a one shot. It is the first one I've ever written and it was done in one session.

Dark tag is for implying certain outcomes.

Alexander suddenly finds himself in the world of Equestria without any explanation at all. He finds himself as one of the Pinkie Pie clones from the episode "Too many Pinkies" and staring at paint. He dares not move as he knows what's coming if he does. With only his knowledge of MLP:FIM and the memories of the clone he now inhabits he has to find a way to stay, while keeping the real Pinkie Pie out of danger as well.

This one, is a hard one.

Featured: (2015-05-14) to (2015-05-18) Thank you all! Also, this story now has a sequel, it's called "This is worse!".

IK+ likes? Holy Guacamole!

All Twilight had to do was finish Starswirl the Bearded's final spell. She didn't have to become undead, seal her soul in the Elements of Harmony, or enlist her friends in an effort to fix everything... but you have to play the hand you're dealt.

Even if it's rotting off.
