Princess Celestia tires of constantly being surrounded by decorum, deference, and formality, and decides to take a day off from being Princess. But visiting Ponyville incognito is harder than she expects. Will she be able to fit in and make friends without blowing her cover?

Discord has a problem. He has a tendency to not think through his actions all that well, poor impulse control, and no ability to figure out how others will feel about what he does. Even with a friend helping him, sooner or later he's going to do something that'll get him stoned or hit with a reforming spell or whatnot. So what's he to do? Ask the smartest pony in Equestria for a solution, of course!

He probably wasn't expecting to get "Have Celestia let you rule Equestria again" for a response.

No one else was probably expecting to enjoy it.

Now with a reading by Crafty Arts!
And a Spanish translation!

Seriously, a lot.

(Now with a Spanish translation by the generous SPANIARD KIWI!)

Spiders. Oh, how I hate spiders. And yet Luna insists on keeping one as a...pet.

Just a little fun story to keep my skills sharp, so don't expect it to last very long!

Okay, I don't know if anyone can hear this, or read this, or whatever, but I'm trying my best to use Pinkie Pie's legendary fourth-wall-breaking powers to try and get a message out.

If you can hear this, I need help. I'm in Equestria, and man, this is strange. But I'm also stuck in Pinkie Pie's body, for some reason.

Yes, it's just as weird as it sounds. And now, I need your help... because all the ponies in this town think I'm crazy!

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.

Pinkie Pie is visited by a strange customer whilst working at Sugarcube Corner. Hilarity ensues.

The glamorous unicorn Opalescence is haunted by bizarre recurring dreams of a world in which she and her friends are all animals. But as vivid as these dreams are, surely they're just dreams, right? There couldn't actually be a parallel universe somewhere where they're little more than pets ... right?

GLaDOS is free of Chell, free to continue testing, when she discovers a portal gun Wheatley tried to repair with duct tape. When the portal gun catastrophically fails, the enrichment center, GLaDOS, and Chell are literally dropped in the middle of Equestria. The mute test subject soon finds the world of ponies far more welcoming than the human world. But GLaDOS sees possibilities. Let the testing begin... for science.

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.
