“Aaaaaaahhhh!!!” screamed a female voice.

The scream was coming from an open portal in the ceiling of a room. It was getting louder and louder as the person was approaching the end. After a few seconds, they came out of the other side of the portal and smashed into an old, wooden table, breaking it into pieces. As for the portal, it disappeared.

“Ow! Dammit, that hurt!” shouted the mysterious being. It had hurt slightly from impacting the table and the floor. “Fucking hell! What the fuck did I smash through?...A table?! How did I end up falling onto a fucking table?! Shit!”

The mysterious being, while complaining, got up from the wreckage of the table with wobbly legs, and started brushing herself off.

“What the…? Why do my hands feel different, and why am I wearing shades indoors?” she asked, confused.

The mysterious being brought her hands in front of her face, and was surprised as their hands weren't hands anymore, they were hooves.

“Hooves? Why would I have…?” questioned the mysterious being.

She then looked herself over.

The mysterious being was surprised that she was a green-colored pony. She sighed. “Of course,” she said.

The green mare didn't look worried at all. Instead, she held an expression that was a mixture between calm and fascination.

“There is no way that I'm drunk from a few sips to be hallucinating that I became Sludge herself. Especially since I crashed through a table and felt it,” said the green mare. Then, Sludge grinned. “This is kind of cool, I guess. One moment I was human and hanging out with my friends at rehearsal, the next thing I know, I ended up going through some random portal and coming out as a pony.”

Back when the green mare was in her dimension, Sludge was the backup guitarist of a punk rock band. After a long rehearsal in the drummer's garage, the band had decided to take a break. She had gone to the kitchen to get the whole band some drinks. While the green mare was in the kitchen, Sludge only had a few sips of alcohol before a portal appeared and sucked her through. Next thing she knew, she fell through the portal and into that room. As for knowing about MLP, Sludge had only watched the show a little since her little brother, Kyle, would hog the tv whenever a new episode would air.

The green mare looked at her front right leg as she moved it around. Sludge then walked a few steps before the green mare tripped over her own hooves and hit the floor with a thud.

“Ugh, on second thought, I guess I should practice trotting,” said the green mare. Sludge then picked herself up. “Besides, it’s trotting. How hard can it be?”


Less than an Hour Later

It turned out to be a little bit hard. Once the green mare had her trotting down, next came galloping and picking stuff up. While Sludge could easily pick things up somehow, the galloping part wasn't easy. It took a lot of tries, plus falling to the floor and dusting herself off, for the green mare to be able to gallop perfectly.

She was relieved. “Now that I've finally stopped falling, I can finally go check out the rest of the place outside of this room,” said Sludge.

While she was practicing her trotting and galloping, the green mare had examined the room she was in. The room was designed for someone or some pony to live in since there was a radio, a bed, stove, refrigerator, microwave, etc, but the room was also run down as parts of the walls were rusted, and there was dirt, grime, and stains in different areas of the room itself, the bed was missing its mattress, the refrigerator and oven were rusted and very dirty, and were missing their doors. On the walls were some posters too, but they were either partly torn or there was dirt covering them, making it hard to read them. There was even some kind of door and a window that viewed some sort of hallway outside the room.

Sludge grabbed one of the table legs and headed for the door, which opened by sliding upwards. “This Equestria seems to be technologically advanced. Hope the locals are friendly, or else I'll have to beat them up,” she said, chuckling. “I hope.”

After trotting out of the room, Sludge ended up in a lit-up hallway that was a little bit run down too.

The green mare winced a little. “Eesh. I feel bad for whoever still lives here,” she said. “This place looks like it’s falling apart.”

Sludge looked at both the left and right hallways before deciding to go right.


A Few Minutes Later

During the time that the green mare was traveling through the hallways, after checking through each of the rooms, she had found some saddlebags, and even though they couldn’t fit around Sludge’s body, the green mare can just use them to store stuff temporarily. Right now, she had just trotted into a room that was filled with old papers strewn about, somewhat rusted filing cabinets, a computer, and other stuff too.

“This is probably the room where they keep the important information. I should find out where I am first,” said the green mare.

So, Sludge then first checked the filing cabinets.

She groaned. “You've got to be fucking kidding me,” complained the green mare.

Some filing cabinets doors couldn't open since they were rusted shut. Some of the papers were too damaged, while the others were too faded to read.

Sludge sighed. “Maybe I'll have better luck with the computer?” thought the green mare.

She headed for the computer to see if it would still work and as soon as Sludge went over to it, the green mare saw something else

“Huh?” said Sludge.

There was some sort of weird device laying right next to the keyboard.

“What’s this?” she asked, confused.

The green mare picked it up and turned it around in her hooves. It seemed to be some sort of weird, electronic legband device with a screen, buttons, and dials on it.

“Cool. Whatever this thing is, it must be very important,” said Sludge. “I’d better test it out first just in case it’s a trap or not.” It did seem quite suspicious to her that something like that was left by itself in an empty room with no one, not even a pony, around.

After the green mare placed the device onto the table, she had to gallop at a far enough distance back and forth a few times just in-case the thing was set to explode when it turned on. That, and some of the buttons didn’t do anything.

“Okay. It has to be this button,” said the green mare, impatient.

Once Sludge pressed the last button, she galloped away one more time. Luckily for the green mare, the object only turned on, but also didn’t explode as it was booting up. Once it was done and nothing else happened, she approached it once more. Seeing that it really was safe, the mare happily attached the contraption to her leg.

The green mare nodded, impressed. “Pretty cool. Can’t wait to see what its functions are, but I’ll have to do that later. Right now, I have to–” she started before being interrupted.

In the hallway came the sound of something walking, and it seemed like it was getting closer to the room.

Sludge scowled. “Shit. Someone’s coming,” thought the green mare. “I don’t know if me not being the only one here is either good or bad, but I’ll need somewhere to hide before whoever that is reaches the room.” She quickly looked around the room before her eyes landed on the perfect place to hide. “Perfect.

The green mare galloped over to the hiding spot and quickly hid there. Eventually, the sound stopped in front of the room door, which opened up. Whoever was making the sound passed by Sludge’s hiding spot, seemingly unaware of her presence. She peeked out see the back of some stallion.

So it was a pony, and from their horn, they’re a unicorn. From what I remember from that stupid show that my brother watches, they’re able to use magic, which is bad for me, an Earth Pony,” thought the green mare.

The moment she saw her table leg weapon, Sludge had an idea. The green mare looked again and saw that the unicorn was distracted with the computer, which seemed to be not only working, but he was also hacking into it.

Sludge then came out of her hiding place, which was the inside of a closet, and headed towards the unsuspecting unicorn, quickly but quietly. “Even if unicorns can use magic, Earth Ponies are stronger. If I can take this pony by surprise, I can knock them out before they can even blink,” thought the green mare. She was lying low in order to avoid being seen in the screen’s reflective surface.

Once Sludge was close enough, the green mare got up. Then, she brought the table leg back, ready to swing.

He smiled. “Yes,” cheered the unicorn.

The reason the stallion said that was because he was able to hack into the system. Too bad that joy was about to be short lived.

“Hey,” greeted the green mare.

As soon as the unicorn heard that, he quickly turned around, surprised.

THWACK!!!

Sludge had then swung the table leg down upside the pony’s jaw, hard. As a result, the stallion fell to the floor, unconscious.

She sighed, and then the green mare threw the table leg to the floor. “Phew. I have a feeling that he’s going to feel that in the morning,” said Sludge. “Now, I’d better see if he has any weapons on him, and then tie him up so he won’t be a threat once he wakes up.”

She went and checked the unicorn’s saddlebags.

The green mare was surprised at what she found. “What the hell?” said Sludge.

Inside of the stallion’s saddlebags were some weird-looking food, bottled drinks, some junk, medical-looking stuff, a figurine of a pink pony, a pistol, some bottle caps, and ammo.

She decided to take the pistol and the ammo and placed them into her own saddlebags. “Good thing I was able to knock him out. Even if there was a chance that he was a nice pony, he would’ve had me at gunpoint,” said Sludge. “I can’t take that chance.”

The green mare then left the room to go find something to tie him up with so that way, when the unicorn wakes up, the stallion won’t be able to try anything against her.

Author's Note

I adopted Sludge from someone on Discord. They have an account called mack.dogg on Instagram.

Sludge was 19 when she was human, while the pony body is in its 20s.

Sludge isn't a fan of the show. She's more into shows like SvtFoE, The Owl House, etc., and anime like Pokémon, One Piece, Toriko, etc.

The reason she has a Pony OC despite not being a fan is that her brother is the one who designed Sludge but gave it to his older sister. He based Sludge on her since he had inspiration to draw a pony version of his own sister. She only accepted it since there was no harm in keeping a drawing that was made by her own little brother.
