Where DO foals come from? The Cutie Mark Crusaders don't know, but they intend to find out!

Twilight and her five friends are transported during a botched spell, across dimensions to... Ponyville, Equestria? But not the same one that they knew. Sitting on a bench is Harpsy and Babar. The Doctoress avoids apples from an aspiring Applebuck. And in a library across town, six stallions join their forces as they try to decipher the appearance of filly look-alikes of themselves around Ponyville!

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.

Twilight isn't having a very good day. An experimental spell blew up in her face, an army of changelings is attacking Canterlot, and she just died. Yet somehow, it looks like it's going to keep going downhill from here.

Given the chance to correct what's gone wrong, Twilight swears she's going to fix all this even if it kills her. Which it will. Frequently.

Captain Rainbow Dash of the Wonderbolts.
Has a nice ring to it, doesn’t it?
Certainly her dream job.
Well, dreams and reality are two very different things.

Especially when our newly minted captain has to deal with an empty roster, budget cuts, the first non-pegasi cadets, and the pressure of finding out your best friend is now your boss, let alone a princess.

If that weren’t enough to make her quit, her three wing commanders might. Cloud Kicker is a sexual harassment lawsuit waiting to happen; Surprise makes no sense; and Lightning Dust is, well, Lightning Dust.

Meanwhile, Scootaloo arrives at the academy, ready and raring to prove she’s got what it takes to be an elite flyer. Pressure mounts as Scootaloo aims to make her hero proud.

There was only one explanation. For all of it. All of the strange, erratic behavior. Her irrational fear of the sun. Her nocturnal habits of locking herself in in the dark and closing all the blinds. Wearing her sunglasses everywhere, even inside! It was time to invest in some silver, garlic, and a wooden stake.

After being sucked into the magical land of Equestria, YOU find yourself as the legendary Brony Hero in this exciting interactive adventure. Will you find the Time Orb and restore peace to the land? Or will you marry Fluttershy? Will you defeat the evil demon king Tirek? Or will you marry Luna?

With 21 endings to choose from, only you can decide your fate!

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?

After being left in charge of Sugarcube Corner, Pinkie Pie enlists the help of her friend Applejack, but after spending quite a lot of time with each other, they discover feelings they thought would never exist. Meanwhile, Rainbow Dash can't seem to shake the feeling that Fluttershy is hiding something from her.

Takes place during the events of They grow up so fast "literally"

Have you ever had a dream that just seemed so real, that it was impossible to say for certain that it was even a dream at all? A dream that, despite all of its impossibilities, seemed to re-write your entire perception of reality, re-writing your sense of what—and indeed, who—you are? Accepting change is hard enough as it is. But when you're a somebody who wakes up as a somepony, how do you cope with the impact such a drastic change has on your mind and body? With changes like these, it must surely just be a lucid dream—albeit a suspiciously accurate one—just brimming with potential and ripe for exploration. So you might as well suck it up and make the most of these distressingly…unusual circumstances, and seize this psychological adventure before you wake up and the dream ends.
After all, this couldn't possibly be real, so the dream must come to an end eventually…right?
