When Rainbow Dash agrees to temporarily care for an abandoned foal, she ends up getting more than she bargained for. Under the scrutiny of the public eye, Rainbow Dash has to try and bring up little Taboo right.

This is an idea that wouldn't leave my head, inspired by Fairy Slayer's "Mommy Nearest," Aldea Donder's "Alicorn," SoundofRainfall's "Play" and RainbowDoubleDash's "Lunaverse"

Alternate Universe: Instead of Twilight Sparkle, Princess Celestia made Rainbow Dash her personal student instead! Follow her through the events of the 1,000th Summer Sun Celebration. A reimagining of "Friendship is Magic"

After a tragic accident, a human ends up in Lord Tirek's body, as part of an attempt to reform the villain after his recent escapades. While the hero of our tale is trying to make sense of his new surroundings, the rest of Equestria thinks that the most terrible threat that their world has ever seen is back...
And the powers that be are definitely not happy about it.

When Gaberdine is awarded a noble title by Princess Celestia, he soon finds out that his new lands contain several surprises. For starters, there is no land in his new barony. Secondly, his new castle turns out to be a broken-down riverboat. And third is… seaponies.

Baron Gaberdine has a lot to learn about his new barony. And himself.

Fortunately, he has a very young teacher.

Fancy Pants and his lovely wife Fleur are quite possibly Canterlot's most heroic duet. Together they conquered countless events, faced hordes of snobbish socialites, and emerged victorious from the most dire of faux pas. May their bravery and finesse be forever remembered on parties to come!

There is a missing element in their perfect life, though: the joy of having a child and becoming a family. When conventional methods fail, will the couple muster enough courage to seek out the alternative, or will they stay a duet forever?

Enter Chestnut—a daring filly from beyond Equestria, out of their social stratum, and definitely exceeding their boldest expectations.

For better or worse.

Octavia and Harmonia Philharmonica were on their way to Manehattan, ready to fulfill their duty as granddaughters and visit Nana. Vinyl Scratch and her brother Long Play were traveling back home from a concert in Canterlot, the first that Vinyl had ever attended. Pure serendipity facilitated these pairs' first meeting.

(Inspired by the pure adorableness that is the cover art)

There are consequences to every action, but we can't always predict what they will be. I stay up at night wondering what I could have done differently, but I've already paid the price for my actions. All I can do now is deal with the consequences, and I've got several great friends to help me do it.

Have you ever woken up as a vegetarian cartoon pony? I have, and she won’t shut up about it. I’m stuck in her body as our minds swap control and our memories blur. I can’t seem to do anything right, and it’s even worse when she’s in charge.

Now, we’re in a back and forth war for control of her body. I just want to eat meat again, and have a little personal space. She’s convinced I’m hitting on her friends and trying to score. I’m not sure I can survive the rest of the day, let alone until we fix this.

V1.2-Pinkie Pie now enforcing RIAA guidelines.

This story is a sequel to Dash of Humanity

I'm stuck in Equestria, which reminds me of the dark ages. Instead of internet and fast-food, I have Rainbow Dash. She's been asked to help me learn to fit in... I'd like a refund.

I suppose we got off to a good start, aside from being told that after all I'd done I'd never see Earth again. So long as I can look on the bright side of life, and not get arrested for running pranks on everypony with Dash, I might just survive long enough to find my purpose in Equestria. So help me, however, if I get any vegetable related cutie marks I will choke a Princess.
