Pinkie Pie hopped around straight ahead on the sidewalks of Canterlot, having to quickly move out of the play for passing ponies. She had moved to Canterlot after her parents living near Ponyville had kicked her out for mutilating innocent animals on their farm, but she didn't care. She was just looking forward to having TONS of fun with the ponies in Canterlot. A couple of days ago, she had arranged to help the teachers take care of some of the brand new little colts and fillies at a small elementary school, and was anticipating it beyond all logical reason. Today was the day, finally the day, when she could take part in one of the most fun things in the entire world, her favorite hobby, the best type of party ever.

Having jumped around the streets for around a quarter of a mile, she finally came across the elementary school she had agreed to come and 'help out' at. It was at a quiet little corner inside the realm of  a colorful fence and gate. Behind the gate consisted of two grey buildings jointed together, one larger than the other, and with a row of flowers leading to the front door of the smaller building, surrounded by playground. It looked like a cheerful place. The ground of the playground was painted with cheerful pictures of trees and happy foals, and trees kept on appearing in random places across the small school.

  Colts and fillies said their farewells to their parents as they ran inside, and Pinkie did the same, except jumping rather than running.

"Welcome to a new year at Royal Palace Elementary School," said the principal in assembly, standing in front of around 400 children. "Now I hope that you had a wonderful holiday, and you must be sad to return to school and have to do work. But don't you worry, because I hope this will term out to be just as fun as your break.

The mare then walked around a little bit, before she motioned through the room for people to come forward through the entrance door. A kindly looking mare was guiding tiny little colts and fillies no older than 5 across the room to the front seats. They all looked so adorable, so much that you just wanted to cuddle them.

Pinkie, who was sitting near the back, was super excited to see the new foals. However, one stuck out in particular. The one that had managed to catch the psychos eye was an irresistibly sweet beige filly. She had a long, yellow and red stripped mane, and turquoise eyes that looked like they filled the entire universe. After Pinkie looked at her more closely, she could see that she was frightened that she was starting school. She was looking down at the floor in the same row as the other foals, and her eyes were droopy and sad.

She suddenly started to weep, audible to the rest of the room. The teaching assistant who was sitting with them however put a hoof on her shoulder, and gently started to rub her back. She quietened down after this, and started sucking on her hoof.

For some reason though, Pinkie felt a little energized and violent by her being in her sight. She just stood out to much, looked a little too different and unique. She was a beautiful child, in an unusual sort of way, but Pinkie knew that she would be the pony who she would party with today. The Cupcake Killer would make sure that the filly she never reached marehood.

The principal droned on about the new students, until she suddenly mentioned Pinkie's name, and how she was coming to help out with the first graders. Pinkie suddenly jumped out of her seat and ran across the hall to the front.

"I am so excited to finally be meeting you all," Pinkie said, a huge big smile plastered on her face. "Oh, and look at those little first graders, their SO CUTE...." She bounced up to them, and started introducing herself until the principal stopped her.

"We are dismissed for today," said the principal finally. "I hope you all have a great year."

                                                                                                  *

Pinkie had been doing a great job pretending to be a genuinely fun and smiley teaching assistant for the majority of the first period. She had played all sorts of games with the foals. Hide and seek, snakes and ladders, all sorts. Unfortunately, her prey for today was nowhere to be seen. She decided to go and ask the teacher where she was so that she could attempt to talk to her.

"Excuse..... I thought there was another filly in this class, the little yellow and red one," asked Pinkie.

"Ah, yes," replied the teacher. "Sunset Shimmer. She's very shy, she's currently outside near the cloakroom, perhaps you could talk to her, you have a real way with things Pinkie." She then smiled, completely ignorant on what Pinkie was really up to.

"Sure will," replied Pinkie. She could not contain her excitement, in fact, she already had a plan that she was going to execute right now. Earlier that day, she had discovered where the kitchen was, and there was bound to be chopping boards, and sharp scissors and knives there. She would then collect skipping ropes from the play trunk in the underground area of the playground, and would tie her up inside a cubical in the soundproof toilets. Then, she could get to work...

                                                                                                                     *

Pinkie quickly collected all of the stuff she needed from around the school and put it in her saddlebag. Luckily, she saw that the beautiful filly was still in the cloakroom crying her little eyes out. She decided to try and make contact with her before she had her real fun. The pink serial killer hopped towards Sunset, and sat right next to her.

"Are you alright?" Asked Pinkie deceitfully.

The cute little filly continued to bury her face in her hooves.

"I wan my mommy," said the little filly, her voice murmured due to her hooves being over her mouth.

"What's your name?" Asked Pinkie. She already knew, but just wanted to seem as normal as possible.

Sunset Shimmer hesitated for a second, and then looked up with tears still stained on her face.

".....Sumset Shimer," she replied in the cutest voice that would make anyone else want to pick her up and hug her.

"Oh Sunset Shimmer," replied Pinkie. The moment was right, she would knock her out now and get started in the toilets.

Pinkie Pie quickly gagged the little filly with her hooves and pulled her up. Sunset tried to scream and wiggle her way free, but it was too late. Pinkie suddenly slammed her hoof down on Sunset's forehead, knocking her out and leaving a massive bruise on her. The fun had just begun.

                                                                                                                 *

When she woke up, Sunset was tied to the toilet seat through a collection of tightly woven skipping ropes. She tried to break free, and then started to cry.

"Mommy..." She cried, tears running down her face like never before.

Pinkie Pie then burst in, scissors and knives clasped in her hooves.

"Oh my god," said the insane serial killer. "This is going to be so much fun."

Sunset Shimmer violently thrashed about in her ropes, tears rolling down her face like never before, and started to scream.

"LE ME FWEE, LE ME FWEE!" Screamed Sunset, trying to bite the ropes free to no avail

"So, I thought long and hard about this," said Pinkie excitingly. "But I decided that the first thing I'm going to do is going to chop of your horn."

Sunset was the very image of terror, fresh tears strolling her face as she started to plead.

"PWEESE, PWEESE, DON DO THIS TO ME!" Cried Sunset.

Pinkie Pie paid no head, as she locked the cubical door, knelt down, and started chopping away at her horn. Sunset wailed and wailed and wailed as the pain shot through her entire body, Pinkie just laughed though, as she could see the knife start to make a mark in the cartilage. She kept on sawing, but because the toilets were in a soundproof area, nobody could hear Sunset scream. Eventually, the horn came off, and Pinkie licked her lips in sadistic pleasure as Sunset cried out in pain.

Once the horn had come off, Pinkie started jumping up and down again.

"Hmm, what should I do next," she said energetically. "I know, I'll start bruising you."

Sunset was just wailing in pain at this point. She knew she was going to die.

Pinkie Pie pulled the chopping board out of her saddlebag, clasping it in her hooves. She then went over to Sunset and smashed her with it. Again and again she struck, leaving bruises every time. After about 20 hard smashingly hard blows, Pinkie reckoned that she had heard at least 5 bones crack. Sunset just screamed and screamed and screamed.

Pinkie then decided to use the scissors, they were sitting all lonely in her saddlebag, and she wanted to put them to use. She got them out, and started snipping away at Sunset's skin by her hooves. Blood started to drip down onto the floor, but it was NOTHING compared to the amount of blood that was about to be spilt. Sunset was shaking and struggling and practically strangling her stomach as she tried to get free. She hit her hooves against the ground tried to rip the ropes apart, but it was no use.

Pinkie then returned to use her knife, and then decided to start cutting away at Sunset's hooves. More wails, more screaming, and more crying was to be heard, and Pinkie loved every second of it. More blood was dribbling down onto the floor, starting to seep out of the cubical and leaving a foul stench.

Pinkie then cackled with joy, and started tearing Sunset's eyes out. Then she threw the torn eyeballs on the floor to the loud racket, and started digging in to the young fillies stomach. She slowly cut through her chest, and could see her organs at work. Sunset was not dead quite yet, but was jolly well near it.

Suddenly, Pinkie threw her knife aside, and started pulling Sunset's organs out with her own hooves, covering herself in even more blood and gore than she already had on her. The blood started spraying everywhere, until Pinkie finally bit on one of Sunset's main arteries. The wailing slowly stopped, and was replaced with an eerie silence, as one huge mega spray suddenly began, and then stopped. Pinkie then heaved out her organs, covering herself from head to hoof in fresh blood.

"Well, I would have preferred it if she's lasted longer," said Pinkie. "But oh well, I'm sure she'll make delicious cupcakes."
