Probably the best story you will ever read. Twilight and the gang engage in an activity at a place at an unspecified time. Some form of emotions and actions ensue and the activity ends at a time that is different from the one where the activity started. Scratch that, definitely the best story you will ever read.

Celestia has had enough of half-arsed promises from her loyal subjects. It's time to wear a different hat.

Inspired by Friendship with Benefits is Magic. Not intended as a direct followup as much as my own take on the idea. What is Celestia to do when Twilight Sparkle shares a little too much? And why doesn't Twilight have any idea what she's talking about? And why is Luna smiling so much!?

Followed up by yet another epistolary conversation between Twilight and Celestia about the magic of not knowing what the hay that other pony is talking about. Features a special guest appearance by naughty!Luna.

Further bulletins as events warrant.

The sequel to Pinkie Pie Discovers Coffee, a series of oneshots show what other horrors will be unleashed on Ponyville as several different ponies try out the Cake's brand new Starbits coffee lineup.

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.

Ponyville is a quiet little town filled with many nice, regular things. But as its inhabitants will soon learn, even some of the most boring towns has their own episodes of just... irregular things.

Especially when it comes from ponies seeking out some sort of unhealthy obsession of theirs...

-A collection of chronologically organized stories where ponies begin to satisfy their hungers for the strangest things.

A 'Know your Star' story; only with your favourite ponies getting unneeded hassle and lies told about them. Won't this be fun? Probably not... But hey, everything can't be seriousness all the time, so let's take a load off and just pester some ponies, and Spike for good measure.

The never ending adventures of Know Your Mare march on and on and on.

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.
