Every season, Rainbow, Pinkie, Twilight, Applejack, Rarity, and Fluttershy get together for their Sleepover.
It's always a night filled with fun. Only, it's a night filled with... a lot of fun. Maybe a little too much fun.
And, believe it or not, by the end of the night...
Even Pinkie Pie just might admit it.

Big, big Special Thanks to Ninjadeadbeard, for putting up with my rough drafts, patiently editing through them, and, of course, for being wonderful friend.

(Ignore the crossover tag it was only needed for passing approval, This story has no actual cross over with Mario or the universe, just references and the beginning scene role-played by the characters in the story.)

Pinkie Pie and Twilight have been role-playing as characters from video games and movies with costumes and all to help them. They have been having fun doing so.

This session they wanted to try a Mario role-play... but what happens when things are taken out of fantasy and into reality?

Celestia has held off telling Twilight Sparkle about her immortal biology for years.

And now that she's told her successor about it... she'll wish she hadn't.

Special thanks to Toriandthehorse, for being a wonderful proofreader, editor, and friend.

After the murder of Rainbow Dash, her ghost feels as though she has not finished her business in the normal world. She seeks revenge on her so called friend Pinkie Pie, and to get her found out before more ponies are hurt.

P.S.
This has been edited with some new ideas.

The Canterlot Castle can be a stressful, boring, and serious place. After already spending what seemed like ages at the dull place to discuss political affairs with the other princesses and make public appearances for the eager Canterlot citizens, Twilight is not looking forward to spending another week there. Luckily, her friend Pinkie comes for a visit to help liven the place up and more importantly spend time with her favorite princess.

After getting embarrassed for the second time in a row at the hooves of Twilight, Trixie goes into a deep depression.
The travelling magician must then ask herself, what's the point in doing what you love when nopony respects you anymore?

(This is a quick one shot on how I thought the episode "Magic Duel" should have ended. The first half of the story is a recap of what happened during the episode. Rated T due to language used towards the end. And special thanks to jmj for all of his support.)

Applejack loves Pinkie Pie, but she's getting awfully tired of the disapproving looks some of the ponies in Ponyville are giving them.

Fortunately, she's done a little research of her own...

Short and fluffy romance, as is my specialty. Long live ApplePie!

Rainbow Dash notices something wrong with Pinkie Pie. What does it mean that her Pinkie Sense has stopped working? Twilight's tests make her violently ill, and reveal a shocking truth...

Fluttershy has been best friends with Rainbow Dash since Flight Camp. It's quite a strange friendship, as no two ponies could be more different. However, what began their friendship is one very, very big thing they have in common: they're both fillyfoolers.
Of course, they're not girlfriends or anything. After all, Rainbow Dash is too adventurous and AWESOME to be tied down or any other mushy gunk like that. I mean, sure they had a sort-of friends-with-benefits thing going on when they lived in Cloudsdale, but that was because they were sort of... well, lonely. By all means the cute, awesome Rainbow Dash should have had tons of friends, but Pegasi aren't terribly tolerant of fillyfoolers, so naturally Fluttershy and Gilda were her only friends, and she theirs. Where else were any of them supposed to get any flank, or for that matter any sort of affection at all?
Of course, Rainbow Dash and Fluttershy stopped sleeping together when they moved to Ponyville to escape all that; nobody knows they're fillyfoolers and they have more friends here, so they're not soul-crushingly lonely anymore. However, Fluttershy continues to long for Rainbow, and not just for the occasional fun night; she's in love with Rainbow, and ever since they were fillies she's wanted to be her full-fledged girlfriend.
However, Fluttershy knows Rainbow isn't interested in anything like that and so hasn't told her the way she feels. However, Rainbow decides to come out to their other friends, and at that moment she's up for grabs; Fluttershy finds herself rivaling Scootaloo, Gilda, and Pinkie Pie for Rainbow's affections. Will Fluttershy find the courage to confess her feelings to Rainbow before it's too late?

Now with a TVTropes page!

Twilight Sparkle has hidden the hottest pepper she could find in Princess Celestia's cake.

This is a bad idea.
