When Twilight Sparkle slipped beneath the covers last night, everything had been fine. She had friends whom she loved, a teacher she adored, and a bright future ahead of her. But when she woke up, her blankets and quilts had been replaced by hospital gowns and padded restraints.

Everything is wrong and nothing makes sense; even her friends have changed. The doctors keep telling her that she is sick, that none of it was real and that it was all in her head. Yet she remembers a life far beyond the hospital walls. She couldn't have made it all up on her own. They must be lying… right?

This story is a sequel to If I Could Catch Fuzz In a Bottle

Twilight Sparkle enlists Rainbow Dash's help in a "Fuzzy Muzzle Nuzzle" research project. The experiment only has three steps. That's not too much to ask of a close friend, is it?

Written for the artist CaptainPudgeMuffin on their birthday, and using their cover art.

The sky ship: a pinnacle of Equestrian technology. With it, unicorns and earth ponies can now soar in the sky. On top of that, it now makes transporting massive amounts of wealth across city lines with a speed never before seen.

With mobile wealth comes pirates.

With pirates, comes the Mane Six.

The hands of the clock keep turning. The passage of time continues its unrelenting march. Twilight and her friends continue to live rich lives, accomplishing their dreams and so much more. Yet, what is Twilight to do when, one day, she realizes she doesn't know her friends that well anymore?

Written for April Fools 2014. A bit of sad to balance out all the shenanigans.

Rainbow Dash charges into Rarity's boutique and announces that she's going on a date. However, when questioned, Rainbow Dash refuses to reveal who her date is. Rarity suspects something is amiss and decides to secretly follow Dash. But what Rarity uncovers is so bizarre, she will never be able to look at her friend, or herself, the same way ever again.

A Diamond Dog king, feeling bold after gathering an army of 100,000 dogs, decides the best way to flex his new muscles would be to invade Equestria for past perceived slights. As such, he sends a letter to Princess Celestia with a declaration of war.

It goes about as well as you'd expect.
