Humans.

Truth or myth? Ancient lost civilization or just an old pony's tale?

No pony has ever seen one, and most haven't even heard of them. But Lyra knows that these wonderful creatures are more than just old legends, and she's going to find out... and possibly drive her roommate insane in the process.

Have you ever been so angry that you turned your faithful student into a princess?

A tongue-in-cheek (hoof-in-mouth?) response to the fandom reaction following the announcement of Princess Twilight.

Twilight Sparkle is officially bored out of her skull. So bored, in fact, that when Fluttershy asks her to attend a dead squirrel's funeral, Twilight can't help but say yes. She's never been particularly fond of the late Mr. Acorn, but with Fluttershy almost in tears, and nothing better to do... well, what are friends for?

A collaborative work with the ever-marvelous Donny's Boy.

<Set before S3E09, "Spike at Your Service"> Rainbow Dash has a problem. She's done reading the last of the "Daring Do" novels, and the next one isn't set to be published until the summer. She tells her troubles to Tank, and in the process realizes that if other ponies can't write fast enough to keep her reading, then maybe she should try her hoof at writing stories of her own. They say to write what you know, and Rainbow Dash certainly does know adventure. But writing about yourself isn't very cool. Tank, on the other hand, is awesome enough to deserve stories of his own, only nopony knows that. Yet.

This story is a sequel to The Sisters Doo

Twilight Sparkle is a scientific pony. She understands things when they are explained.

Pinkie Pie is... uh... not a scientific pony. And she can't explain anything.

But there are secrets in the Wabe that Twilight needs to know, and only Pinkie has the answers.

A side-story to "The Sisters Doo".

Daring Do seeks a favor from her sister in Ponyville. Due to buried grudges, things quickly get out of hoof. She soon finds herself on her most perilous mission yet... with her biggest fan in the world. In the midst of truth and lies, loyalty and treachery, love and hate, one thing is clear ― some family situations are stranger than fiction.

The story extends in Through the Looking-glass and What Pinkie Found There and The Daughter Doo: Honorary Cutie Mark Crusader.
