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.

It is the day of the Summer Sun Celebration, and Princess Celestia is coming to Ponyville. Twilight Sparkle is overseeing preparations yet again, and has meticulously planned every last detail to ensure that everything is perfect for her mentor's arrival. Nothing is going to go wrong.

Except when the big day comes, Twilight has gotten four hours of sleep and Fluttershy is nowhere to be found. Pinkie Pie sets off after her with nothing but a dark coat and the voice of a chain-smoking stallion, and the Apples and the Carrots are at each other's throats while Rainbow Dash is attempting to fill in for Fluttershy.

As her plans collapse around her and Ponyville descends into chaos, Twilight Sparkle must focus on obtaining the one thing that can set everything right: the all-powerful, awe-inspiring magic of caffeine.

Six Star Equestria Daily Feature

One by one, Twilight and her friends must come to terms with the consequences of being the Elements of Harmony.

These stories take place in the intervening time between Season One and Season Two,
with the exception of Ditzy Doo: Muffins, which takes place early in Season One.

The series continues in the sequel, Secrets and Lies.

Pony Psychology has a TV Tropes Page.

A fellow pony notices that Princess Luna may have a serious problem: there is a small, sentient race inside her mane and they have been living there for quite some time. Luna must decide what to do about this.

"My name is Lyra Heartstrings, and you will not remember me. You won't even remember this conversation. Just like with everypony else I've ever met, everything I do or say will be forgotten. Every letter I've written will appear blank; every piece of evidence I've left behind will end up missing. I'm stuck here in Ponyville because of the same curse that has made me so forgettable. Still, that doesn't stop me from doing the one thing that I love: making music. If my melodies find their way into your heart, then there is still hope for me. If I can't prove that I exist, I can at least prove that my love for each and every one of you exists. Please, listen to my story, my symphony, for it is me."

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!

Octavia is a high-class pony. Fine alcohol is her wont, and uncouthness her intense chagrin. Such is her surprise to find herself lumbered with an insufferable oaf of a DJ pony. However, sometimes these situations work themselves into a satisfactory ultimatum all the same.

After reading a book by Spitfire's personal trainer, Rainbow Dash decides that the best way to get closer to her ultimate goal of joining the Wonderbolts is to add strength training to her practices by having one of her friends ride her. However, when she decides that Twilight Sparkle is just the mare for the job, the pegasus gets a bit more than she bargained for.
