Unglued
"Come on, you two! Hurry up!" Kimono called out, running along the walls, and leaping from surface to surface. "We must save Applejack, before it's too late!"
"We're coming, we're coming!" Waterfire called out trying to catch her breath. "Good grief, how in the world does she MOVE like that?"
"Guess we shoulda taken those karate lessons like she did." Minty replied, galloping along as fast as she could. "Hey Kimono, wait up!"
The three hurriedly ran from room to room, With Waterfire tampering with the locks to open the different doors, and Kimono taking out the remaining gizmonks with several well-placed kicks. But the factory was a large building, and they couldn't seem to find their missing friend anywhere.
"Keep looking, girls!" Minty yelled, galloping along and peering into every doorway she passed. "AJ's gotta be in here somewhere!"
.....
Meanwhile, the mare in question that they were looking for, was currently strapped to a table in a laboratory on the second floor. All around her the lab gizmonks fiddled with dials and buttons on all sorts of consoles and strange machines.
"Uh, look, guys?" Applejack asked nervously, struggling against the restraints that kept her strapped down to the table. "You sure we can't talk this over?"
"I am afraid not, my dear Miss Jack." Dr. Strangehate replied coldly but politely, as one of his assistants flipped a switch on one of the devices. A huge buzz saw lowered down towards Applejack's midsection, it's sharpened blade spinning so fast it looked like a metal blur. "Now, let us find out if that wonderful immortality, also grants you any degree of invulnerability, as well."
It was at that exact moment that the door exploded inward, and three mares came barreling into the room. Kimono sent the three assistant monkeys flying into the wall, while Minty dove onto the table where her friend was strapped down.
"Applejack, noooo!" The green pony cried out, putting herself between the lowering blade, and AJ. "I won't let you hurt my friend!" Surprisingly, the blade miraculously stopped spinning mere inches away from the two ponies.
"W-what the hay just happened?!" Applejack whispered in disbelief, looking up at the sparking cutter hanging mere inches just above the mares. "Minty, are you all right?"
"Fascinating... it appears the green pony's presence caused the blade to malfunction. I wonder if she has some kind of probability manipulation ability." The monkey speculated, even as he was running for the door. "I'd love to stay and test that hypothesis, but this untimely pony rescue tells me it is time for a hasty retreat!"
"Oh no you don't!" Applejack snarled, pulling at her restraints like a mad pony. "Waterfire, get me loose, quick!"
"Okay, I'll give it a try..." The other mare hit a few buttons with her hoof, and the restraints came loose. "but what are you-"
"Get back here, you damned little monster!" Applejack howled, galloping after the fleeing primate. "I'm going to rip your flanking head off!"
"Now what in the world was that all about?" Minty asked in confusion, hopping down off the lab table. "She didn't even stop to say thank you!"
"I'm sure Applejack has her reasons." Kimono said, looking around at all of the terrible lab machines of torture and death. "Ugh... say, Waterfire? You know all about all the dangerous chemicals and toxic fumes in your sewer, right?"
"Yeah, but why do you ask?" Other other mare replied, puzzled.
"Is there a way you could, I don't know... fiddle with a gauge here, pull a lever there, let some chemicals loose, and BOOM?" The oriental pony asked.
Waterfire stood silent for a moment, before her eyes went wide in realization. "You-you want me to blow this place up, don't you?" The blue mare nodded her head slowly. "It could be done, but shouldn't we get everyone out of here first?"
"Agreed. Minty, go make sure the factory's clear, then get AJ and meet us at the exit." Kimono told the clumsy mare that was with them. "We're gonna make sure the gizmonks get a really big bang outta this one!"
...
"Hold it right there, you filthy little poo thrower!" Applejack screamed, finally cornering the sinister simian on the catwalk. "You're not getting away, after all the innocent ponies you turned into paste!"
"Don't you dare try to lecture me, you four hooved oat-slurper!" Stangehate, snarled, looking back at the mare with contempt. "I was simply making use of the resources I had on hand- namely, a bunch of degenerated pony who don't even count as sentient beings!"
"My friends are not a commodity you can just use like that!" The red mare snorted, stamping her hoof. . "You going to pay for your stupidity and greed!"
"I came here under Princess Luna's personal request, and I am under her personal protection!" The bespectacled primate warned, taking a step backward. "If you so much as lay a hoof on me, I'll make such a diplomatic stink at the court at Canterlot, that all of Equestria will never live the shame down! Your ruler will have no choice but to burn Ponyville to the ground to save your citizenry from the dangerous 'mutants' who attacked my factory, and killed my workers!"
"Who says you're going to get anywhere to cause any kind of stink, Strangehate?" AJ asked coldly. Before her opponent could even react, the red earth pony charged forward, smacking into the gizmonk, and sending him tumbling off the catwalk.
"Progresssss!" Strangehate howled as he plunged downward, before landing in the vat of hot and sticky glue with a loud blorp! Applejack stared down at the disgusting swirling mess of white glue and fur with contempt, feeling no sense of satisfaction with her deed.
"Well, at least it looks like the monkey... has been spanked."
"Applejack, thank goodness I found you!" Minty called out, running up to her friend on the catwalk. "We gotta hurry up and get out of here, Waterfire's about to make this place blow!"
"Lead the way, Mints!" With a nod, the two ponies want galloping off the catwalk, and raced for the exit below.
.....
It was a bizarre sight, for the ponies of Equestia- to see the ground to the northwest of the Ponyville suddenly explode into a strange gushing fountain of glue, sewage and dirt. although the mighty blast was heard as far away as Baltimare, it was surprisingly not massive enough to cause any damage to the nearby Ponyville itself. The massive gaping whole it left behind, however, had reached downward deep into the earth, and hot boiling magma rose to the surface to fill it in. Generations from now, after natural magic and the elements had reshaped the landscape, ponies would come to call this place the crater- and later the volcano- of gloom.
But for now, all that mattered was that a crime against ponies the rest of the kingdom had all but forgotten about, had finally been brought to a halt. And as three mares celebrated their victory as they made their way back towards Ponyville a fourth very angry red pony was planning on having a few very angry words with a certain alicorn princess of the night, who had allowed this evil into their midst...
