Twinkie Pie. Appledash. Rareshy. You know these pairings and may have favorites of your own. But what if every member of the Mane Six were paired with every other member in the same fanfic?! That's what the Combinatorics Project is--an epic treasury of fifteen ships spread across five parallel universes increasingly full of plot and whimsy. Can you guess which couple is which?
* The angster and her secret admirer
* The burlesque showmares
* The celebrity marriage
* The commune farmers
* The curse victim and caretaker
* The dessert caterers
* The hopeless homebodies
* The industrial mavens
* The mad scientists
* The masquerade hosts
* The model train overlords
* The multiversal adventurers
* The orchard grafters
* The rivals in love
* The weather aficionados
Plus: Twilight blows up like a balloon and goes out to 'have a spicy time'! Applejack and Rainbow Dash are competitive about everything! Rarity dresses like a butterfly--and later in five outfits at once! Pinkiezilla crushes a miniature town and argues with Octavia about her instrument! Fluttershy dances with an angel and keeps a weather diary! Derpy tells a six-word joke! Not everypony ends up happy, but most do! A little suspense is a good thing. Bitter sorrow! Transcendent joy! Probability cupcakes are cupcakes that cupcakes!
Note: This story was written during Season Two, so a few small things are out of date.

Wings, Magic, and Friendship combine to rule the skies.

Against impossible odds and armed only with skill, wit, and faith in each other, these two little ponies will honor their duty to defend the kingdom against a relentless enemy. Together, the fastest flyer in Equestria and the most powerful unicorn of her generation will show the world the meaning of Equestrian air superiority.

Rainbow Dash once bragged that she could clear the sky in ten seconds flat, but this time she's clearing out more than just clouds.

Left only with a promise to keep in touch, Rainbow Dash struggles to convey her feelings, and to figure out what the words were that she couldn't say on that last snowy night at the train station before Twilight left. As everyone slowly drifts apart, Dash will have to put in the effort if she wants to keep her friends together.

How dare she come in here like I had nothing better to do than to drop all my orders and bow to her whims! I've never barged into the weather office to demand a sunny day when one hadn't been scheduled! Where does she get off demanding things from me? It's as though she knew I would stop whatever I was doing to make her happy. The painful part was, she was right.

Twilight and Rainbow Dash, together? Must be that 'opposites attract' thing. Then again, maybe they have more in common than they're letting on...

An ongoing series of slice-of-life snapshots. RD, I said to keep the Library clop-free, not... oh, forget it!

All chapters originally written as separate entries for flash-fic blog Thirty Minute Pony Stories (TMP). I highly recommend a visit to TMP if you're looking for some of the best 1000-word gems in pony fiction. Many thanks to TMP for inspiring me to write!

Epilogue - The next Daring Do book isn't out yet, so Twilight convinces Rainbow to read a romance novel instead. That never works - does it?

Second - Twilight reads everything she can get her hooves on. Sometimes she finds things she'd rather not know, or in this case, that Dash would rather not know.

Becoming Daring - The latest Daring Do novel isn't quite what Dash expected, and her reaction isn't what a friend of hers expected, either.

Firelight - Not every schedule has to be full and not every list has to be checked off.

Lift, Weight, Thrust, and Drag - Dash's friends can't save her from an anniversary date with Twilight, at which she will show Twilight a secret skill she's kept from everypony. Twilight's definitely not complaining!

The Wait - Agony is knowing the one you love is standing hoof to hoof with danger and knowing there's absolutely nothing you can do to help.

Hoofing It - One day, Twilight will learn that reading Daring Do alone won't get Dash to do everything. That day is not today.

Variations on a Theme - How many combinations of Twilight Sparkle and Rainbow Dash can there be? Plenty!

Reluctantly Yours - There's something Rainbow Dash doesn't want to lose, and Twilight refuses to let it go. Will this be the end of the awesomeness that is Dash?

Closer to Home - Giving up one dream to keep another isn't always a bad trade.

Wings, Wonderbolts, and You - Always read the fine print. And the rest of it, too.

Pinfeathers - Dash was all she ever wanted and all she'll never have. Twilight hasn't lost Rainbow Dash, but someone has.

Daring Do and the Chapel Perilous - Something's wrong with the Daring Do fanfic Dash and Twi are reading, and it's not funny.

Pew! Pew! Pew! - Rainbow Dash finds new and unexpected uses for the Elements of Harmony.

Less of Me - Twilight decides to help Dash's career along, but she might be getting ahead of herself.

The Ink Wasn't Even Dry Yet - Dash and Twi go head to head in a battle for the ages! And oh, the stakes...

Audience - Twilight Sparkle doesn't dance. We hope. Dear heavens, please let her not dance.

The Trip and the Destination - Dash took on one storm too many and Twilight's had enough of it.

A kind chap by the name of munngojerrie graciously offered to do a dramatic reading of Egghead and Featherbrain. It's done, and it's an hour of audiobook shipping goodness your ears will thank you for! Take a listen to part 1 HERE and part 2 HERE and part 3 HERE.

What do you do, after you've made the impossible, possible?

With the Wonderbolt tryouts looming just around the corner and rumors of Spitfire being able to perform the Sonic Rainboom at will, Dash is at wits end. She needs something greater, awesomer, more epic than just a mere Rainboom. After all, to perform that trick a second time would label her a one trick pony and if Spitfire could pull it off, then what was the point?

So what trick could possibly be greater than a Sonic Rainboom?

Rainbow Dash isn't having a very good day. First she was in some dark place, then it turns out she's in the hospital. Oh, and she's apparently blind now.

Eventual Twidash!

Rainbow Dash doesn't like anypony touching her hooves for a reason. While at a slumber party at Rarity's, Rainbow's closest friends are about to find out just what that reason is. She only wished that it was simply about getting the hiccups.

As the sun gives way to the night, a pegasus knocks on a window. She has a secret. One that, if revealed, would shame her forever. Yet she can't stay away.

Twilight has an experiment planned, and it centres on Rainbow Dash.

As anxious as she is, Dash really has no right to complain.

It was her idea after all.
