As I said above, Pinkie is my favourite pony, and I tend to read a lot about her when I feel in the dumps.
A smile is all it takes (Multi-chapter. Incomplete)
This was one of the first fics I read on FIMFiction, and probably the only Pony on Earth story I follow rapturously.
Just Smile (Multi-chapter, Incomplete)
I love this story because it captures perfectly the true spirit of Pinkie Pie: always smile, always try to bring light into darkness, sometimes literally.
The Brightest Timeline (One-Shot)
A little fic with an ending I totally didn't see coming. It surprised me a lot, and left me thinking deeply for a while.
Pinkie Predicts Predicaments(One-Shot)
A nice little story about Pinkie and The Cakes.
Pink and Famous (One Shot)
If you, like me, are a person who dreams of gaining fame one day; you may feel identified with Pinkie in this nice little story.
Pinkie in a rainy day.
Equestrian Pie (One-Shot)
This is a sad one, but American Pie is other of my favourite songs, so I'm glad to find a pony version of it.
Pinkie Pie Is and Eldritch Abomination (One Shot)
Beware, this story contains existential horror. But, if you are into this kind of stuff (like I am sometimes) give it a try.
A sweet little story set during Pinkie's birthday (not Party of One)
Gallop from the Ghosties!(Multi-chapter, Complete)
It turns out that Pinkie is scared of ghosts, after all.
More Than Her Mane(One-Shot)
If you like Pinkie with straight hair (and I said Pinkie, not Pinkamena), maybe you'll like this one.
A Day In The Life(One-Shot)
A normal day in the life of Pinkie Pie.
Normal? Are You Crazy?! (One-Shot)
Pinkie Pie acts completely normal... wait, what?
I wouldn't know how to describe this one, so just read it.
Fancy That (Multi-Chapter, Incomplete)
Pinkie Pie and Fancy Pants. Crazy enough to work.
