It's Nightmare Night, a time of treats and tricks. Fluttershy decides that maybe she should stop hiding in her house and get into the Nightmare Night spirit! But she doesn't know how to make a good prank or give a good scare. So, she decides to consult her best friend Rainbow Dash.

Pinkie: Spectacularific! Let's do it!

A hack author (from "Extremely Terrible and Horrifying Stories" and "Mystery Pinkie Pie Theater 3000") is attempting to write his next magnum opus. Then Pinkie Pie happens.
Not the most original idea in existence, but hey, this is my take on how it would play out.

On a seemingly normal day in Ponyville, Twilight is extremely excited when she finds Pinkie Pie deeply enthralled with a calculator, writing down what appears to be very advanced algorithms.

Twilight is determined to find out what said algorithms mean, and what mathematic talent her friend may possess that she never knew of before.

"Oh," sings Pinkie Pie, "Today's a day of laughs, a day of jokes...a day for pranking lots of folks!"

Yet an plea from Applejack keeps Pinkie from helping Rainbow Dash with their planned prank. As a conspiracy is revealed Pinkie Pie's friends try their best to put one over on the greatest prankster in Equestria...but will Dash spoil it?

Professor Dusty Tomes, Equestria's greatest scholar and Twilight Sparkle's childhood hero, arrives in Ponyville on a mission from Princess Celestia. He must study a unique phenomenon: a being whose inexplicable powers may have the potential to benefit Equestria—or even to destroy it. The object of his research? The cheerful, exuberant pony known as Pinkie Pie.
