Twilight finds a dusty old book full of puns and begins to use them, much to the dismay of her friends, considering her puns are slowing down their travels and they need to be PUNCTUAL.

The title says it all. By the way, I was absolutely hammered when I wrote this. Don't say I didn't warn you.

After her first time donating blood, Fluttershy saw something that convinced her that Nurse Redheart is a vampony. Teaming up with Twilight Sparkle, the two try to prove and disprove, respectively, the vampony status of Nurse Redheart. Of course, all this must be done all while trying to avoid raising her suspicions.
Which, of course, cannot end well.

It is the summer of 2020. The popular TV show "My Little Pony: Friendship is Magic" has finished its eighth, and what appears to be final, season. In the wake of increasingly violent attacks by an extremist Internet-based terrorist group, the founders of the popular pony site, Equestria Daily, decide enough is enough. Bronies from all over the world have gathered in a small, abandoned industrial park in the run-down outskirts of Chicago to find the culmination of their dreams: Equestria. Through the wonders of science, they flee Earth for a land of magic, mystery and secrets. They will be weighed, they will be measured... will they be found wanting or will their dreams come true?

Story Idea inspired by a chapter in Shipping and Handling by PegasusRescueBrigade.

Twilight Sparkle and the gang go paintballing. Of course, there's no entertainment without the use of paintball miniguns or paint grenade launchers, right? Twilight soon discovers that while friendship may be great, shooting someone in the face is a hell of a lot more fun. Although these ponies are the very best of friends, there can only be one winner. While the result is uncertain, there's only one thing that's for sure: hilarity and plentiful amounts of paint shall ensue.

After an unknown accident Twilight Sparkle and Rainbow Dash awake to find themselves sharing the same body! Now they must struggle to hold themselves together as their world is turned upside down. How long can two ponies exist in a single mind? It’s a race against time as they search for answers before it’s too late. When all is said and done, you’ll never look at Twilight Dash the same way again.

The unthinkable has happened. A new Draconequus has emerged, apparently intent on plunging Equestria into chaos once more. To make matters worse, Pinkie Pie is nowhere to be found, forcing Twilight and the others to scramble to find a way to defeat this new threat without the Elements of Harmony.

Meanwhile...

After strange dreams, Pinkie Pie awakes and finds herself in the body of a Draconequus. Between strange new powers that she can't control, and, for some reason, an inability to communicate with other ponies, Pinkie finds herself alienated from her friends... but finds help from an unexpected source.

Pinkie Pie gets her friends to explain various aspects of Ponydom to the audience (aka a wall of Sugar Cube Corner's kitchen). A silly story poking fun at some of the fan-produced elements of MLP.
