Sometimes you just need to scream. Fluttershy knows this.

"Ponies just bursting into song in random places at the drop of a hat? Who does that?!" were her exact words while in Manehattan.
Yet shortly after her visit to the big city, Rainbow Dash wakes up one morning unable to stop spontaneously singing.

Perhaps the city left a bigger hoofprint on her than she'd like.

For those of you who read my recent blog, this is not the romance fic I was talking about. This was just a contest entry that I decided to put in.

After a midnight journey to a school, Applejack and Rainbow Dash discover an magical and amazing artifact awaiting them.
A oneshot with heavy Harry Potter references, but not enough to be called a crossover.
(P.S. Try to spot the mention of Derpy!)

Rarity desperately needs "a little something" for her super secret project. Pinkie Pie really needs to stock up on Gummies bizarre food. They both need these things from the Everfree forest, so they decide to go together. However something goes horribly wrong... They both realise that they have switched bodies, and so a hilarious adventure ensues as they try to live each others lives whilst trying to find a way to reverse what happened in the forest...

Pinkie Pie and Rarity's Nightmare Night party is coming up. Pinkie wants a nice, silly party, while Rarity wants a fancy soirée. Who will win out?

Written for One-Shotober.

Rarity helps Pinkie out by kissing her boo-boo. This is totally okay and not awkward.

Warning: Shipping. So much shipping.

Taking a big chance, Rarity decides that Hearts and Hooves Day is the perfect time to tell one of her closest friends who she really feels about her. A box full of homemade chocolates and heart full of hope see her on her way. Plus some help from Pinkie Pie.

Pinkie isn't shy. If there's one thing Pinkie isn't it's shy, so then why is she getting all flustered around her BFF Fluttershy?

When Fluttershy confides her love for Rainbow Dash, all does not go smoothly when her friends try to help, and it seems Fluttershy isn't the only pony keeping a secret.
