"Cupcakes are the children of cakes! Cupcakes are the children of cakes! CUPCAKESSSSS... are the children of caaaakes!!!!!!" Pinkie sang in the park. Nopony even flinched. They knew this was typical Pinkie.
"Hi, Bon-Bon-Bonity-Bon-Bon!" Pinkie started hugging the mare. Bon Bon grunted. "Can't...breathe...Pinkie." Pinkie let go instantly. "Oopsie daisy! Sorry!" Bon Bon gasped for air as Pinkie bounced away.
"Hiya, Dinky!" Pinkie yelled as she spotted the purple filly.
"Hi, Pinkie!" Dinky called back. Pinkie stopped and chatted with Dinky, until the unicorn had to leave. Pinkie hopped along.
"Hello, Random Hoo-Wait..." Pinkie inspected this blue hoodie. It drooped over her hoof. Why is this perfectly good hoodie in the park? Pinkie wondered. "Aha! You're the litter hoodie! You make sure nopony litters!" She knew it! But wait, why would this hoodie watch boring ponies when it could be eating cake? It just didn't make sense.
Pinkie looked at it some more. It was telling her take it, to put it on, she knew it. "Must...wear..." The pink pony drooled. She put it on, and it felt perfect. Pinkie hopped along, in her brand new jacket. When she got to the statue of the mare with the flag, she stopped. Lollipop? the Element of Laughter thought looking at the flag. But no, it was not a lollipop. Aww... Pinkie was sad now. I wish the flag was a lollipop.
Instantly, the flag turned into a lollipop. She scooped the lollipop up. This didn't happen before... Pinkie shrugged. She must have just imagined that. Pinkie had what her PFF, Twilight, liked to call an "over-active imagination". But just to be sure, Pinkie tested it out again. I wish that I had four leaf clover designs on my hooves. It worked! The mare stared at her hooves. I wish that me and my besties lived in Candyland It didn't work. The magic must have only change things into other things.
Pinkie ran over to Twilight's house. "HeyTwilightwhatwouldcausemetosuddenlybeabletochangethingsintootherthings?"
"Huh?"
"Thanks, bye!" It was just like Twilight said, it was the hoodie. She stared down at it long and hard. She would have to change other things too!
When she passed by Derpy delivering the mail, Pinkie halted to a stop. I wish Derpy had regular pony eyes, like me! Suddenly, Derpy's eyes rolled around to a normal position. "Derpy, can you pretty please get Twilight, Applejack, Rainbow Dash, Fluttershy, and Rarity to meet me in front of Sugarcube Corner in an hour? Thanks!" Pinkie was too excited to stand still. She bounced over to Town Hall. Bon Bon and Lyra were there chatting. Bon Bon as usual, was frowning. I wish that Bon Bon has a happy and perky disposition! Bon Bon started hopping around smiling like crazy.
"Bon Bon, are you okay?" Worried Lyra asked.
"I have never been better!" Bon Bon giggled, even though her eyes said "Celestia help me, I'm going insane."
Pinkie skipped away. This day could not get better!
The pink pony was almost to Sugarcube Corner when she heard her friends talking. Rarity seemed to be the one speaking at the moment. "It was so weird, Derpy's eyes were nor-."
"DEAR LUNA!!! WHAT THE HAY HAPPENED TO YOUR MANE AND TAIL, PINKIE?!!" Rainbow Dash interrupted. Pinkie giggled. On the way, Pinkie changed her mane and tail to a bunch of different hues. She also changed the style. "Oh, I changed it, using my magical hoodie!"
Twilight frowned. "Magical hoodie?"
Pinkie nodded. "You know, the thing I told you about earlier?"
"Oh, so that's what you said!"
Applejack grinned a "Sorry, don't kill me" look. "Uh, sugarcube, don't ya think that's a little dangerous?"
Pinkie Pie scowled. "What do you mean?"
"We mean, what if ya hurt somepony?"
"WHY AREN'T YOU GUYS SUPPORTING ME?!" I wish that my friends' personalities are exactly like mine! All of the Elements of Harmony except Laughter's mane and tail poofed up. They all started doing stuff Pinkie would do. Except one...
"UCK! Pinkie, have you not learned one thing? I DO NOT approve of this mane at all, DARLING!" Rarity's face turned red. Pinkie gulped. "DON'T YOU EVER DO THIS AGAIN!! GIVE ME THAT HOODIE NOW!!!!"
Trembling, Pinkie asked "H-how are you not affected by the magic?"
"I have dealt with DARK MAGIC like this before. NOW HAND IT OVER BEFORE I GO OVER THERE AND GRAB IT MYSELF!!!" Pinkie quickly handed it over.
And then Rarity broke it in half, reversing all magic. Pinkie died a little inside.
All of her friends looked dazed and confused besides Rarity.
"NOW DON'T YOU EVER WEAR THIS HOODIE AGAIN!!!!!!!!!!"
Author's Note
It is done! And incredibly stupid! Comment below if you see any typos! 
Pinkie frowned. It had been a week since the hoodie incident and Rarity was still not talking to her. Pinkie could still see the disappointed and raged looks on their faces when Rarity explained what happened. The mare knew that the hoodie corrupted her, but she didn't feel like explaining it to them. She stared at the bench where it all started. Pinkie sat down on the bench, feeling the cold metal. She closed her eyes...
"Excuse me, did you happen to see a blue and gold hoodie?" Pinkie opened her eyes with her jaw opened. There in front of her was a peach mare with a brown bun. She looked like a scientist with her lab coat and atom cutie mark.
"Well did you?"
Pinkie started to talk but her mouth could not seem to form real words. "B-b-y-u-."
The mare's eyebrows creased as she looked more worried. "Oh no, my boss is going to kill me!" She started trotting around, looking for her hoodie. Pinkie finally managed to speak. "WellyouseeItookitandfoundoutithadmagicalpowersandIuseditonmyfriendsandmyfriendtoreittopieces." She finished. The mare looked at her, with misery. "Well," the unicorn sighed. "Might as well tell you the whole story."
"My name is Atom Quake. My boss and I have been working on a project for the past 10 years to make the ultimate army to help Equestria. It was supposed to change things into other things, like Equestria's armies into giants, and the enemy's armies to ants.
I was told to go to the park and test it out. Somehow, it got lost and you managed to get your hooves on it." The mare sighed. "Well, time to go back in time and correct that mistake." Before Pinkie could say anything, Atom Quake pressed a button on a watch that Pinkie only noticed right then and opened a portal. "Goodbye." Atom said. Than everything went black.
