Ever wonder how Equestria's most loved party pony went insane? Ever wonder how "Cupcakes" came to be? Well, it all goes down to a simple pegasus pony from Cloudsdale; Surprise. After she opened a bakery in Ponyville, Sugarcube Corner didn't get any more customers, and was going out of business. Surprise was even starting to take over Pinkie's role as Ponyville's party pony. Even the Rainbow Dash, Twilight, Fluttershy, Applejack and Rarity seemed to hang out with Surprise more than Pinkie. It didn't take long for Pinkie to snap.... to become a heartless, bloodlusting monster that is Pinkamena.
