Twilight cast a spell and got herself turned into a filly. Luna has tricked Celestia into believing there is no cure, and now as Luna tries to 'find a cure' Celestia has to look after Twilight the Alicorn; filly version. And heaven knows Alicorns are not born often for a reason.

Twilight Sparkle was quite positive she could handle the job of teaching young unicorn students in Ponyville how to handle their new magic, but when the school’s traveling magic teacher returns to town as scheduled, a series of miscommunications and accidents nearly drive the two of them crazy. Only the power of friendship (and a certain amount of tinkering from the townsponies) can save the day for them and their students before complete disaster strikes, but maybe there is a little more than friendship in store for the two young teachers.
[Comedy][Education][Slice of Cake] Featured on Equestria Daily. With a TV Tropes page and two sequels, The Traveling Tutor and the Diplomat's Daughter and The Traveling Tutor and The Royal Exam.

A lighthearted look at education, young love, dating and buckets of water in the face in that most normal of all small towns, Ponyville.

Caution: Contains bananas, marble chips, jogging, matrimonial planning, romantic interference, intrigue, lesson plans and lots of nuts. A whole town full of them.

Rated I for Innuendo, some drinking, some sleeping together (Just sleeping! Really! Why won’t you believe me?) and a great deal of dunking in the town fountain.

No cupcakes were harmed in the production of this fic. However, a great number were eaten. And they were yummy.

In the warmth of her cloud home, Rainbow Dash is about to turn in for the night when she hears Scootaloo crying outside in the middle of a vicious blizzard. Plucking the freezing filly from the snow, Rainbow hopes to provide some much-needed comfort for the otherwise tough young pegasus, but she uncovers a disturbing reality that she knows she cannot handle alone.

Knowing only one pony that could really help her out, Rainbow enlists Twilight’s help, determined to set things straight for Scootaloo. But what Rainbow doesn’t know is that in her efforts to provide a better life for the filly, her friendship with Twilight will develop into something more.

This story is a sequel to The Monster in the Twilight

Now that Luna has returned to the throne, and the aftermath of her brief appearance as Nightmare Moon is being cleaned up, the story is over. Right?

Not quite.

Twilight Sparkle had nearly been destroyed in the chaos of Nightmare Moon’s return, but now with the assistance of her five friends, she is facing a fascinating new world filled with wonderful things. No longer the scarred monster who nearly destroyed Canterlot and raged through the Everfree Forest for over a decade, now she has been healed by the Elements of Harmony and is living at the edge of town with her adoptive mother Zecora. Not all the fears of her past can be left behind that easily though, and now she must face the consequences of her actions as she faces the most daunting challenge of her life.

Ponyville.

Letters is a sequel to the alternate universe story The Monster in the Twilight. In this story, Twilight Sparkle exchanges letters with Princess Luna, two ponies with a common problem of fitting in and making friends after the destruction of Nightmare Moon.

Normally I would try to talk you into reading the sequel even if you haven’t read the original story, but in this case, you’ll probably be more confused than entertained. But go ahead. I don’t mind if you don’t read the first story. You’ll never find out what an Urlock is, but that’s fine. It’s your funeral.

After a long day of fun, Applejack holds her girls during nap time.

We all know the story of how the Princess’ young student and five friends defeated Nightmare Moon and brought Princess Luna back to our lands. But what if the tale were false? What if the young Twilight Sparkle on the event of her entrance exam had not been rescued by Princess Celestia, but instead lost her mind among the power of her youthful surge and had to be sent away, far away before she could destroy all of Canterlot with her newfound power. Now the feral unicorn prowling the Everfree Forest only vaguely remembers her past, slipping away from constant terrifying attempts to capture her.

And she is beginning to remember what true power felt like.

Inexperience is a foreign concept to Celestia. At least she thinks it is. Right up until the moment a rash decision leaves her with a student who is a dozen years younger than what she's used to.

Enjoy.

Main Course is a successful chef and restaurant owner. Or he was, anyway, until a fire tore up his life's work and left him adrift. When he visits his sister in the rural backwater town of Ponyville, he discovers an abandoned building that's perfect for a quick fix-up so he can flip it for a profit. But the building comes with an unforeseen tenant, and when he lets her stick around he discovers that maybe, just maybe, there's something out there more important than wealth and fame.

If you ask Applejack, she’ll tell you Pinkie Pie can be a few apples short of a bushel even on the best of days. They’ve always been good friends, but nothing more than that. After all, what could a hard-working apple farmer and a sugar-crazed party pony possibly have in common?

As it turns out, the answer to that question may not be a pleasant one, but something good may yet come of it.

Twilight gets a feeder to study birds.

She also bought a ton of seeds for it.

While she's frustrated at the fact her supply seems to be disappearing into thin air, she's about to realize that she has a much bigger problem on hoof.
