"Everything was black. Twilight couldn't see her own hoof, even if she pressed it against her face. Only the occasional strike of purple lightning broke the impenetrable darkness."
"Who turned off the sun?"
"Pinkie, you ruined my third-pony narrative!"
"Third-pony what-a-tive?"
The two ponies kept shouting at each other, each having no clue which direction the other one was in. Finally, a bright, purple flash ended the realm of darkness and brought them somewhere else. Both of their senses were temporarily impaired, although Twilight could clearly feel the grass underneath her hooves. When her senses returned, she saw an expansive grass field with a huge castle looming in the distance.
By the time both ponies were perfectly healed, someone approached them from the back.
"Who the hay are you?" Pinkie quizzically asked. In front of her was a tall, blonde young man wearing a green tunic and carrying a sword sheath with on his belt.
"Hyeh!" the boy yelled.
"Pardon me?" Twilight wasn't sure if he was injured or if he just talked like that.
"Hyeh!" he repeated.
"Uh, sir, we appear to be lost in some sort of alternate universe, so if you'd just kindly--" Twilight was interrupted when she saw the long, slender sword two inches from her face.
"Hyeh!" the boy yelled again, this time sending out a tiny, blue ball with wings.
"This looks like a rather weak equestrian demon. Its stubby hooves make it useless for combat or escape. I'd say it'd be easy to kill."
"Kill!?" Twilight immediately protested. This wasn't part of what she'd expected to happen. Without second thoughts, she dashed off in the other direction. Pinkie followed her when the sword pointed towards her.
Twilight and Pinkie were faster than the boy expected. He grabbed a small ocarina and began playing a simple melody. Within seconds, a horse of his own had galloped next to him, already equipped with a saddle. The boy hopped on and ordered his horse to follow the ponies.
When Twilight heard another pony's hooves clopping on the ground, she looked back and saw that the green-dressed boy was quickly gaining on them. Without warning, however, another portal appeared right in front of Twilight and consumed her and and Pinkie. It closed less than a second before the boy's sword jabbed the thin air where the ponies where before.
Back in the pitch dark tunnel, Twilight was relieved to have avoided that sword. Once again, a bright flash brought them to their next destination, temporarily blinding them again. This time, the first thing Twilight felt her hooves make contact with was a cold, metal floor.
Twilight looked around the room she was in. The walls were crowded with vines, and the place utterly reeked of emptiness. A single plaque hanged on one wall.
Welcome to the Aperture Science Enrichment Center. Everyone is guaranteed to die have a great time while they experience what it's like to be a scientist!
Twilight grew nervous at the words on the plaque. It reminded her of those places that claimed to be family-friendly but actually had something evil behind them. That's when Twilight noticed the talking sphere behind her.
"Space, I wanna go to space, space is fun, will you take me to space? SPAAAAAAAAACE!!!"
"This thing is funny!" Pinkie Pie giggled while listening to the robotic voice's rambling.
Twilight looked around for another portal, since this room had no doors. Finally, she saw a blue portal around her elevation on the wall. Upon jumping in, she found herself at the other side of the room.
"What? How'd that happen?" she questioned. When Pinkie Pie's attention diverted to Twilight, she kept flipping back and forth to the Twilight in either portal.
"Neat! I want to do that!" Pinkie Pie exclaimed, bouncing up and down and jittering all the way. When Twilight finally exited the orange thing she had somehow went into, Pinkie began running through the blue portal repeatedly.
"This is fun! Awesome! Cool! Pinkie-licious!" As Pinkie kept teleporting, she entered a different pose each time she came out of the orange portal.
The combination of the robot's habit of yelling space and Pinkie's joyous laughter made it impossible for Twilight to concentrate. It was like trying to explain indoor voices at a sports rally.
"Enough already! I'm here trying to figure out how we got into this mess, and more importantly how we'll get OUT of it, and you two won't stop making noise!"
Both Pinkie and the sphere stopped moving and stared at Twilight. Great. Now their staring was driving Twilight's mind blank.
Finally, after several minutes of sitting there and coping with the unusual silence, Twilight heard Pinkie scream and point and shout at something.
"Twilight! I see the purple thing! But it's shrinking!"
Without any warning at all, Twilight tackled into the hole. She didn't care about anything besides getting out of that maddening room.
"That was fun, Twi! Where do you think we'll go next?" Pinkie asked.
"I don't know, Pinkie. I just don't know."
