What are the chances your favorite pony was secretly a changeling all along?

Yeah, probably about one in one.

A letter from Celestia interrupts one of Pinkie's parties with disturbing news. Now friendships will be pushed to the limit as Twilight struggles to uncover which of her friends is not who, or even what, she appears to be.

(While not a romance, this does contain a shipped pair)

Lonesome Has Finally Reached Whispering Sands and has came closer to his goal. Along the way he's picked up a mare, Cinnamon, who's very existence has plagued him since he found her lost in the desert out side of town. But She turned to be more use full than he thought. Now all he has to do is survive her mother. Good luck Lonesome after all, Hell Hath No Fury Like That Of A Women Scorned

The Eleventh Doctor (aka Matt Smith) is bumbling about in his Tardis when a crazy timey-wimey happening finds him in Equestria, a land from a children's cartoon. Despite the idea that being in the world of TV ought to be impossible, he's found himself turned into a bowtie-wearing pony in a pleasant little town known as Ponyville. What's more, the people there won't stop calling him Doctor Whooves! In order to get bet back into his own Time Lord form and out of the impossible world of My Little Pony, he may or may not have to make some new friends, fight some villains and pull out his "savior of the universe act." Geronimo!

This is a different take on Doctor Whooves, and also a sleep-deprived Doctor Who/MLP crossover idea I got in the very early hours of the morning so it could easily be rubbish. It's not meant to be terribly serious, but it's also my first fic so go easy on me. More characters could come and the rating could possibly change.

Scootaloo's birthday is coming up, and Rainbow Dash is unsure of what to get her number one fan. Upon asking her, it seemed her birthday wish would be a little harder to obtain than Dash thought. Enlisting the help of Twilight, the two mares set out to ensure that little Scootaloo has the best birthday ever.

That's right, a fic about best filly where nothing bad, tragic, or otherwise horrible happens to her, or anypony else. This is my attempt at an episode like fic.

Special thanks to RazedRainbow for getting this thing ready for public consumption.

Everypony has a special connection with their friends, sometimes before they've even met. What most ponies fail to realize is that this connection will always be there, no matter what happens. Or fails to happen.

A speedster fails to break her barriers, and in so doing learns how to move them.
A timid animal lover, prevented from following the dreams she only just found, resolves to chase them anyway. 
Two tearful foals meet, forming a partnership more enduring than any mountain.
A country mouse adapts to the city, and discovers how to bring two worlds together.
And a lonely filly fails her trials, only to pass the greatest test of all.

Though Rainbows may hide from the weather, Harmony knows not defeat.
For Magic may bind souls together, but Friendship makes it all complete.

Twilight Sparkle thinks that Cheerilee would provide a very interesting partner... to talk to... about literature. Nothing else. Right?

Due to her reckless antics and tomboyish behavior, Rainbow Dash has generally been thought of as one that had no real interest in the matters of love and dating. However, she gets challenged by Spike one day when he tells his friends that he would never be able to fall in love with her. Given Rainbow's competitive nature, a new challenge between the two of them begins.

She tries to steal Spike's heart and if he falls in love, he loses!

Between awkward dates, friendly interference, a jealous Rarity, an over-protective Twilight and a betting pool stretching all across Equestria, who knows what ending awaits them!

A cutie mark appears on a pony's flank when he or she finds that certain something that makes them different from every other pony.

But you knew that already, didn't you?

But what you didn't know, perhaps, is that a common past time is guessing what a pony's cutie mark stands for. This is a story about one such game.

Written for a creative challenge and a contest on Reddit.

As a descendant of the greatest conjurer of the pre-classical era, Star Swirl wishes to live up to her namesake's reputation and their shared cutie mark. But how can she emulate a powerful unicorn when she is an earth pony? Taking the advice of her psychologist, she heads off to Ponyville to try and find out.
