Twilight and friends learn that prolonged exposure to the power of Pinkie Pie can cause some rather interesting side effects. An unbearably silly idea that wouldn't go away until I wrote it down.

Twilight Sparkle. A name known to everypony in all of Equestria. She's saved Equestria multiple times now, and with her and her friends being the Elements of Harmony, as well as being Princess Celestia's "Most Faithful Student", she enjoys a great life.
But what was before that? Follow her on her journey through foalhood, and her times as Celestia's Student.

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

Yeah, probably about one in one.

[Featured on EqD and FiM Fiction] It is that time again, the dreaded flu season. Not even Princess Celestia, the ruler of the sun and day, is safe from it. When Celestia contracts the flu, what pony could possibly nurse Celestia back to health? Why none other than her dear, loving sister of course! Enter Nurse Luna!

Between crazed guards, a palace staff desperate to please their rulers, and a crazed unicorn running around, no pony is safe from this madness.

This story is a sequel to When the Man Comes Around

The sixth story in The Journey of Graves.

Spring has come and gone, Graves remains in Ponyville, and for once, all is well. No monsters to slay, no damsels to rescue, nothing: just nice, relaxing days passing in easy leisure. Or, at least as relaxing as Ponyville ever gets. A collection of short stories, the marshal takes a break from fighting and learns a little more about his friends and neighbors, one lazy summer day at a time.

The Changelings have been defeated and Shining Armor and Princess Cadence have said their vows, but that still leaves the Mane Six and others with the issue of the strain on their friendships. And among all the guests present at the reception, a few of them are going to be suprised with what new relationships are formed.

A live reading by Alchemystudent is available here.

Rarity's family name is in shambles, and her fortune is nonexistent. To return what her father squandered, she and her good friend Pinkie Pie turn to piracy, commandeering a magical airship and kidnapping the princess's personal student.

When Princess Celestia learns of Twilight and Applejack's abduction, she doesn't agree to pay the ransom. No, she hires the sky's greatest tactical mind, the Daring Swordspony Rainbow Dash, and her sidekick, Fluttershy. As the two groups engage in a game of cat and mouse, more dangerous threats hang on the horizon. Aztec Curses, angry gods, and a mysterious figure known only as the Derp Pirate Roberts.

Will the six Elements of Harmony be able to gather the seven pieces of eight, or will the world fall to utter chaos, and rise up as an empire of anarchy and piracy?
