"Yippie! Yippie! Time for the after party! I cant wait at all!" Pinkie pie said, bouncing up and down and up and down. 1 HOUR LATER... "Where is everypony? Oh great. WELL I guess i can wait 4 hours more..." Pinkie pie sighed.
4 HOURS LATER...
"OMG THEY'VE BEEN GONE FOR 5 HOURS!!! S-should I c-c-call the po-o-olice?" Pinkie pie screamed. "Wait... They didn't come to the A-after party because they h-h-hated me? I was t-t-too ann-n-noying? *sniff*" Pinkie pie cried. "Fine. I'll give them the pinkie THEY want. No more Miss Nice pony. NOW IM PINKAMENA, MURDERER OF PONYVILLE."
And that's how pinkamena was made. Permanently. Really. No more pinkie pie. It's pinkamena forever.
