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?

Twilight Sparkle's imagination as a child was unbelievable, probably due to all those books. Which also make up the amazing Fort Book, Twilightopia's first stronghold against the country of Armor! With the help of Captain Smartypants and Private Cadence, General Twilight defends her fort against her brother's advancing army of one!
A tale of Twi's childhood told from her point of view.

Inspired by the cover picture.

Twilight used to think she could handle stress pretty well. The smartypants incident however proved her wrong. So she decides that when her friends aren't there she needs somepony there to help her through the stress.

So what does our lavender librarian do?

She creates an artificial intelligence.

Pinkie Pie gets her friends to explain various aspects of Ponydom to the audience (aka a wall of Sugar Cube Corner's kitchen). A silly story poking fun at some of the fan-produced elements of MLP.

This story is a sequel to My Little Heartbreak: Creativi-Tea

For the whole of April, Heartbreak has been confined to the library under Twilight’s orders. By the time May starts, being cooped up is starting to give her a serious case of cabin fever. Heartbreak wants some open space, some fresh air and a bit of grass under her hooves. Twilight wants Heartbreak to learn a bit more discipline and honesty about things. The two would butt heads, but Twilight finds a compromise.
Send her off to help Applejack with the first season’s apple harvest!
But how will a pony like Applejack, whose motto is, “Honesty is the Best Policy,” deal with a pony like Heartbreak, who has wrapped herself up in webs upon webs of lies just to cope with her situation?

When Dialga and Palkia start to attack one another in Alamos Town, a Ponyta named Flare Blitz is caught in the crossfire. After falling into the dimensional rift, he finds himself in a strange new land filled with brightly coloured ponies. Flare doesn't know how he got here or if he can even get back home...

The question is, will he even want to go home?

Edit: So I finally got offa mah flank and started the re-write. I want to give massive props to Blazinblade7 for editing as well as my little bro, who is teaching me a great deal of authory stuff.

This story is a sequel to Petriculture

It's been several months since Pinkie Pie made a stunning admission about her past that permanently changed her relationship with her friends, particularly Twilight Sparkle, but life seems to have settled back to normal (well, normal by Pinkie Pie's standards, at least). However, when an old nemesis returns and ensnares Twilight in her influence, it's up to Pinkie to make things right.

This is the second story in The Petriculture Cycle. There is a TV Tropes Page for the entire Cycle here.

In an effort to keep her mind occupied, Twilight Sparkle decides to delve once again into the grand mysteries of Pinkie Pie. This time, Twilight's focus is on her claims of growing up on a rock farm: like so many things related to Pinkie Pie, the idea that somepony could grow rocks as an agricultural product makes absolutely no sense. However, the investigation eventually leads Twilight to a rather... surprising discovery.

This is the first story in The Petriculture Cycle.

Artwork by Page Turner. Now with a TV Tropes page.

Cheerilee is a sheltered, over imaginative, home schooled filly about to start her first day at Ponyville Elementary. Lyra is an energetic hooligan with a keen interest in the unusual. Bonbon is a clueless, young pony who somehow gets pulled into her childhood friend's shenanigans. And Derpy is a clumsy, young pegasus with a troublesome past.

What happens when these four fillies are placed into the same classroom along with several other unique students? The past happens—er, happened? Just read the story...

After the disastrous invasion of Canterlot, an injured changeling wakes up near a small cottage and is quickly discovered by two of the last ponies she ever wanted to see. Now, with the help of her new "friends," she has to remain undetected in a town high on changeling hysteria that would not hesitate to throw her in the Canterlot dungeons should her true nature be revealed.

Simple, right?

Too bad she couldn't have picked a worse form to stay inconspicuous...
