The Pyro and The Engineer's Misadventures in Equestria

The Pyro entered Twilight's library, then picked the bag he left behind. He threw items out of the bag, looking for something. Nothing of use. Nothing. Well, that's until he picked up something large. It was his Strange Backburner with the Hale's Own rank. He started chuckling, which turned into a maniacal laugher.

"Who is there?", a voice said, apparently comming from upstairs.

Pyro immediatly sprinted out of the room, leaving behind a faint trail of blue confetti. Spike came from the staircase, wondering what happened. Pyro's bag had it's items spilled around. He approached it, and tried to look around for tips. He then noticed something that had a smell. A way too good smell. The smell that remembered him of somepony. He tried to think deeply, until he muttered something.

"Trixie.", he said. "I must warn Twilight!", he continued as he started running towards Ponyville.

Somewhere deeper into Ponyville...

"Hey, Pyro, I found a good place to stick those banners!", Pinkie said. The REAL Pyro followed her. Pyro started immediatly placing one of the papers, and smacking it with his Neon Annihilator. All he did was to damage a pole and to ruin the paper, and to cause some of the ponies to give him a frightened look.

"No, not like that, silly! Here's how you do it!", Pinkie said as she placed a nail on top of one of the papers. She picked a hammer, then started smacking the nail.

"How in the world can she hold the hammer without fingers?!?!", Pyro thought. He was confused. But he decided not to let confusion take him down. He began to place the posters on the wall, and sticking them with the nail. Nice. Pyro noticed the sun was reaching the horizont. He and the rest didn't had much time before the party would ensue. And he was not sure if the princesses actually supported the party. However, his Spy-senses immediatly stung. Wait, how the hell could the BLU Spy reach this place? Oh, right, the teleporter. Still, none of the BLUs would even be interested on entering the building the teleporter was. The cap was alterady taken. He shook his head. Maybe it could be just him getting insane. Not every day you get warped to a strange town full of talking mystical creatures that were labeled as non-existant, right?

Meanwhile, on the other side of town...

Trixie held the Backburner. She wasn't sure if it would work, she had to gather a group of angry ponies, and lead them into the REAL Pyro. Problem is, she didn't even knew where Pyro was. After all, Pyro was teamed up with Pinkie, and she was completely random. It was impossible to deduct where Pyro was. She would just have to run around, hoping that she would reach Pyro, hide, and let the mobs attack the real Pyro. Plus, she couldn't let anypony else see her. Well, it would be centered around luck. She pressed the trigger. Flames started erupting from the dragon-shaped nozzle, like it was a real dragon. According to her plan, the ponies looked with a terrified look at the 'Pyro'. As she wanted, a small group of ponies picked their torches and pitchforks, then started heading towards her. She then got her hoofs - I mean, hands - out of the trigger, then started running around the alleys. Unfortunaly for her, the ponies started to have trouble reaching her. "What? They're alterady giving up?", she thought. She started to run slower, allowing for the slow-mo group of ponies to keep up with her. She just hoped not to run into the Elements, Lyra, Engineer or worse, Pyro.

Somewhere on the farmlands...

"Dammit. I can feel a spah 'round here.", Engineer said as he stopped sticking one of the posters on a tree.

"What do ya mean?", Applejack asked.

"I can feel whenever someone's disguising. I alyways can.", he answered. "I'm feelin' it right now. Dammit, never thought that BLU Spy could reach me here.", he continued.

"But what's the problem with someone disguising?", she asked again as she picked another piece of paper.

"Well, ya see, the BLU Spy can disguise and infiltrate my base. Lately, after dealing with enough spies, I learned to feel whenever anything disguises as one of my 'team'. I felt that feelin' again, therefore, either the BLU Spy came here, or some of the ponies here can disguise.", Engineer answered.

"Well, there's a hoss in town that contains this ability. She might be the one who disguised.", Applejack said as she started smacking the nail with her hammer.

"Damn! I just hope she doesn't uses it for malicious purposes.", Engineer said.

Meanwhile...

Rainbow Dash was cruising the airs of Ponyville. She was proud of having the task of spreading the banners, after all, that was her speciality. She then noticed two Pyros on town: One next to Pinkie, and another being chased by an angry mob of ponies. "What the...", Rainbow said. She suddently noticed Spike running. "Well, maybe he can explain me this.", she said as she started approaching the ground.

Spike was running like mad trying to reach Twilight and others to warn them before Trixie could actually cause any damage and blame Pyro for it. He was startled by Rainbow Dash suddently landing on front of him.

"WOW! You scared me!", he said.

"Hey, Spike. You won't believe what I saw!", Rainbow said, completely ignoring what the dinosaur said.

"What?", he asked while rolling his eyes.

"Two Pyros!", she said. Spike's eyes widened.

"Oh! One of them must be Trixie! She went to the library, and stole something from Pyro's backpack!", he said.

"Oh, that explains.", she continued.

"We need to tell Twilight and others about this, and quick!", he said.

"Hop in!", Rainbow offered. Spike jumped in her back, unsure about what she would do. Suddently, she started flying. Spike never knew she flied THAT fast. They arrived in the Sweet Apple Acres in less than 20 seconds.

"Hey! Is Twilight inside?", asked Spike, still dazed.

"Yeah, she, Rarity, Fluttershy and Lyra are getting the place ready for the party.", Engineer answered.

"Ok, thanks!", Spike answered as he and Rainbow runned in.

"Do ya know why they were looking for Ms. Sparkle?", asked Engineer.

"I dunno. Maybe it's about the impersonating problem.", answered Applejack.

"Ok, the chairs, tables, play room and mostly everything is done. We only need the decorations!", said Twilight. Rarity was about to open her mouth, but was interrupted by Spike and Rainbow.

"Twilight, somepony is impersonating Pyro!", he said.

"What?! Who?", asked Twilight.

"Your nemesis.", he answered. Twilight's shocked eyes instantly became enraged eyes.

"Her.", she said. "Ok, you girls take care of the party. I'll take care of that ungrateful showboat!", she continued.

"Wow, I never expected such thing.", said Lyra. Rarity nodded.
