Pinkie Pie and Rainbow Dash were waking through the weather factory, Pinkie admiring everything that she saw. She watched how they carefully shaped each individual snowflake. She watched how they created the clouds with a puff of smoke. Everything took so much time an effort for something that she saw every day. Soon they came to her favourite part of the factory. The rainbow pool. The swirling waters of colour were so hypnotising, she wondered how something so beautiful was created. She gently placed her hoof in and watched in awe as the glorious ripples spread through the colourful liquid. She brought her multi-colour hoof up to her face and examined the rainbows in all of their glory. She wondered what something so beautiful could taste like…
Without hesitation, she licked some colour off her hoof. It was the most delicious thing that she had ever tasted. The flavour spread around her mouth, covering her taste buds in the most wonderful of ways.
“Rainbow Dash, what is this made of?” She asked. She looked at Rainbow and immediately felt scared. Rainbow’s usually kind face had developed into a malicious smile.
“Can you keep a secret?”
"Dashie, you're scaring me." Said Pinkie. Dash had a wicked expression on her face. Her mouth was spread into a devilish smile and her magenta eyes were nearly red. Pinkie backed away, eyes shut in terror.
"I won't hurt you. I just want to show you my secret. You trust me, don't you?" Said Dash in a murderous tone. "Just come with me."
"Okay I'll do anything! Please don't hurt me..."
Dash walked up the stone steps to a black, decaying building, Pinkie following closely behind.
"Welcome to the rainbow factory."
How could a place so dismal produce something so beautiful and pure? Thought pinkie.
As they walked through the doors into the morose building Rainbow Dash said “We can’t have any pegasi who failed their flight test to put a bad name on Cloudsdale.
“What happens to them?” Pinkie asked in horror.
“Let’s just say, they serve a much better purpose.”Rainbow said suspiciously, before adding in a evil tone, “Especially the colourful ones.”
A horrible feeling dawned over Pinkie. “You aren’t saying…”
Before she could finish, a rainbow-covered worker called out “Dash! Scootaloo escaped again!”
“That little BITCH!” Shouted Rainbow. “I’ll find her and make sure that she never escapes again!” Rainbow sped off through the building. Pinkie began to feel light headed.
“Please…tell me.. that this… is just… a bad… dream…” Suddenly, everything went black. Pinkie awoke to high pitched screams and shouting.
“Help me Pink…” Rainbow Dash had clamped her hoof over the struggling filly’s mouth, gagging her and making her unable to speak.
“SHUT UP!” Shouted Rainbow Dash “WE CAN’T HAVE PEGASI WHO FAIL THEIR FLIGHT TEST PUTTING UP A BAD NAME FOR CLOUDSDALE!” Tears fell from the silenced filly’s eyes as Rainbow Dash pushed her along the floor. Without even trying to, Pinkie felt herself rise from the floor and follow Dash into another room.
Inside the room was a large, dark machine with many blades. A bucket was placed underneath. On the wall were foal sized shackles to hold a struggling pegasus to the wall.
“Watch closely Pinkie. This is how rainbows are made.” Rainbow Dash forced the struggling pegasus into the machine and laughed wickedly. “Nobody can help you now Scootaloo.”
Screams echoed around the room as the blades whirred, slicing the filly to pieces. Pinkie Pie tried to run but her legs wouldn’t let her. “Beautiful, isn’t it Pinkie.” Pinkie tried to open her mouth but she couldn’t. Tears streamed down her cheeks as she watched the pegasus that she liked so much get brutally murdered.
After the screams stopped, a quiet trickling was heard. Rainbow Dash leaned forward to grab the bucket. “What a beautiful orange. Don’t you think so too Pinkie?” Rainbow held the bucket towards Pinkie’s face.
Pinkie felt sickened, knowing what she had eaten. But she still couldn’t deny the fact that she wanted more.
Pinkie pie burst into tears. “C-can I dr-drink some?” She stuttered. “Please?” She then screamed and shook her head. “NO!” She shouted at herself. “WHAT THE FUCK IS WRONG WITH ME?”
“It’s okay Pinkie. That’s how I first reacted. We all have a dark side. There is absolutely nothing wrong with you. Go on, drink some.” Rainbow said casually.
Without even thinking about it, Pinkie Pie put her head in the bucket and began licking up the enticing liquid. Before she knew it, the bucket was empty. She felt horrible knowing what she had done, but she needed more. She wanted the machine.
As if she was able to read Pinkie’s mind, Rainbow made pinkie an offer. “600 bits for the spare machine. It’s a lot smaller and it should be easy to secretly take home.” Pinkie nodded reluctantly and said “I have the money at home. Can I pay you back?”
Rainbow laughed and nodded. “Pinkamena Diane Pie. You have officially found your dark side.”
Rainbow left the room for a few minutes and came back with a small machine. A complete replica of the one in the middle of the room. “There you go.”
Pinkie walked home with her head down, thinking about what she was doing. She didn't want to hurt anypony. But the taste of rainbows... anything was worth that.
She placed the machine in the corner of her bedroom at home, ran to her bed and burst into tears. What could she do to not hurt anypony and still taste that beautiful flavour? Suddenly, an idea hit her.
“I’ll do it in a way that won’t hurt anypony!” She said to herself. “I’ll wait for the news of a death in Ponyville, I’ll go to the graveyard, dig them up, and use them to make rainbows! Pinkie Pie, you are a genius.
