Sunset Shimmer, Twilight Sparkle, Pinkie Pie, Rainbow Dash, Applejack, Rarity, and Fluttershy were walking to the workout room where Flash Sentry was punching a boxing bag with his hands in boxing gloves. They were going to prank him by putting a laxative in his water bottle. Everyday when Flash works out, he takes water bottles with him to dehydrate him to get rid of a sweat.
Sunset Shimmer was carrying the laxative in her backpack, so Flash doesn't see it. She and her friends walked in. "Hey there, Flash, how's it going with you working out so much?", she asked.
"I'm just trying to lose weight, girls.", Flash said. "Me and my band are taking a break from making music."
"I bet the sound of your guitar sounds pretty amazing.", Twilight remarked.
"Thanks, Twilight from... this world.", Flash said. "Look, I know your not the one I love so much which is from another dimension and you like that guy who runs Camp Everfree. But, do you want to talk for a bit?"
Twilight looked at her friends, then she agreed. "Sure, I guess it's about time we talk to each other after a while.", she said. She and Flash walked out and closed the door behind them.
"It's your cue.", Applejack said.
Sunset opened her backpack and took out the laxative she's about to use. She ran to Flash's water bottle, removed the cap, and poured some of the laxative liquid into the bottle. "It's done then.", she said as she screwed the cap back on the bottle. She grabbed her laxative bottle and put it back in her backpack.
Fluttershy wiped some sweat off her forehead. "Phew, that was close.", she said with relief. "How did you do everything that fast?"
"We never seen you prank anyone before.", Rarity said.
"Back at the alternate universe with all of the ponies, I used to prank Princess Celestia by putting laxative liquid in her drink before taking a sip.", Sunset said. "She always has her face in the sun while her eyes are closed."
"If she's a princess, would she get really mad at you.", Rainbow Dash asked.
"It's really funny at times.", Sunset said.
"So, if you did those pranks, were you pranking us the whole time when you turned into that raging beast?", Pinkie Pie asked. "We all fell for it easily."
"Oh, that wasn't a prank, I was literally trying to kill you all.", Sunset said. "I haven't done a prank since that day."
Twilight and Flash came back in. "You can have her back now.", Flash said.
"What did you and her talk about?", Applejack asked.
"I told her about how I got interested in music and she told me about how everyone in Crystal Prep bullied her.", Flash said.
"I remember that, you wanted revenge on them after turning into that evil version of you.", Flash said.
"Principal Cinch was the one to blame, she was the one who wanted her to do that.", Rarity said.
"She tore dimensional holes around us in the air and the ground with her powers, even destroyed our statue.", Rainbow Dash said.
"Couldn't there a way to rebuild it?", Twilight asked. "I hope it doesn't cost a lot of money to have it fixed."
"Don't worry about it, Twilight, we'll figure a way out to fix it.", Fluttershy said.
Flash picked up his water bottle and drank some of his water. He tasted it. "Tastes funny.", he said. "I thought water tastes normal."
"I just drank water earlier and it tastes fine.", Applejack said.
"Well, it's talking to you, Flash, we'll be heading out.", Sunset said. She put on her backpack and she and her friends walked out the workout room.
Flash put his boxing gloves back on and continued to punch the boxing bag. The others watched through the window and giggled.
"How did it not come to him yet?", Pinkie Pie asked. "Oh my god."
Flash paused and felt his guts rumble in his stomach, he removed his boxing gloves off his hands, and held his stomach. He's about to poo. He ran out of the workout room and into the bathroom.
The others followed him to the bathroom, but stopped when they saw the men's bathroom sign. Sunset snickered and did a move where you push something out of your butt.
Rarity covered her mouth with both hands, trying to hold her laughter. "I never seen someone poop that hard.", she said.
"That was only twenty-five seconds we waited for that to happen.", Rainbow Dash laughed.
"He might want to change his pants if he pooped his pants.", Twilight said.
They laughed a little louder causing Flash to hear them outside the bathroom. "Are you girls laughing out there, what was in my drink?", he asked.
"You guess, man, you were the one who drank it.", Pinkie Pie said.
"Did you freaking put a laxative in my drink?", Flash asked.
"Oh, well then, Pinkie, so they were your laxatives.", Sunset laughed. She and her friends burst into laughter.
"You got to be kidding me!", Flash yelled. "Crap!"
"We got you, Flash.", Applejack laughed.
"That wasn't funny, that was stupid.", Flash snarled.
"Go take care of yourself, dude.", Twilight laughed as she and the others ran off laughing. "You might want to clean your pants later."
They stopped at a corner in the hallway and caught their breath. Sunset was amused. "Well, I'm satisfied of what happened.", she said.
