"I mean, wouldn't you do the same thing about me?" Mabel would admit that she was shocked to hear about Stars betrayal, but she couldn't really blame her.

"Of course, I would, but you're my twin sister! She messed with my sanity for a friend!"

"Are you saying you wouldn't do whatever it took to keep Wendy safe?"

Mabel watched as Dippers retort died in his throat. She could tell that he was hurt by Star but he needed to realize that she had no other choice.

"Look, I'm not saying Star did the right thing. In fact, what she did was really messed up. But she came clean and we can assume that Marco is now paying for it.

"She sacrificed her friend's well-being to make sure we have the best chance of defeating Bill in a few hours. We need to make it count."

He nodded in defeat, but apparently had one more question on his mind.

"Do you think Star will come out to battle Bill? Or do you think she will stay out of it in an effort to appease Bill?"

Now it was Mabel's turn to hesitate. Would Star return to help? What if she decided to aid Bill during the siege to atone for breaking her deal with the demon? From the stories Star told her, her magic could obliterate the Mystery Shack Attack Force.

"Honestly?" Mabel saw no reason to lie to her brother, but she thought it'd be best not to voice where her thought train was heading.

"There's no reason to worry about it too much. It's out of our control."

"You're right. I think I might be able to get a few hours of real sleep haunt-free now." Dipper let out a huge yawn and Mabel noticed just how tired her brother must be. The bags under had long since been upgraded to full sets of luggage. Star really knew how to cause some damage; it was a wonder Dipper was even standing.

They walked to the sleeping tents together. Mabel ignored all the foreboding shadows on the path, instead taking the opportunity to be thankful that she had her brother by her side.

The pyramid was blotted the stars behind it. It was a black hole that had sucked the whole town inside of it, but now the town was fighting back.

Dipper had to admit he was feeling better. Just a few hours of sleep had done a lot for him. Dipper could think more clearly. He was still haunted by Star's actions. He wasn't sure how to feel about it, but at least he was more prepared to cross that bridge when they got to it.

"Ah hoot-n-nani! Let's get this show on the road!" Fiddleford was manning the main station. Dipper had no idea how the man knew what all the levers did. There were at least twenty of them, all pointing in a different direction.

Dipper turned from the window and surveyed the command room. Fiddleford was at the control center, ready for action. The multi-bear was already relaying messages across the Shack through the stringed cans. They were all doing their jobs, but Dipper had yet to properly do his. They couldn't survive without a leader.

Dipper walked to the 1MC (points if you guys know what this. Hint, it's with ships) that'd been set up and thought over the speech he'd made up in his earlier. It was garbage. He thought back to all the times he'd try to tell Wendy how he felt about her. They'd all been forced and awkward. That shapeshifter had forced him to come up with the courage to just speak from his heart. It was when he spoke with emotions, not carefully choreographed vocabulary, that he was able to best express himself. Best thing to do then was wing it.

Dipper crumpled the paper and threw it away, there would be no running back to the safety of a prepped speech.

"Um… Dipper here. Just wanted to let you guys know what's up." Dipper had no idea how the guys in the movies made it look so easy. His hands were already clammy. He took a long breath.

And slowly released it. His hands unclenched. He had this.

"This is it, guys. This is what we've been preparing for. The enemy is right around the corner. Beyond us lays the gates of hell.

"They are trying to take over our world. This isn't an invasion, though. It's an extinction plan. If Bill gets what he wants, humanity as a whole will cease to exist. Those that survive will only be a husk of what we once were.

"We are the what's standing in between Bill and his goal. And every creature in that palace is what's standing between us and survival. And to be clear, when I say creatures, I mean those freaks from outer space. If you are in the Mystery Shack, you are family. Period.

"No matter what happens, protect one another. We can do this." The cheers reverberated through the walls.

"That was one honkie tonk of a speech, kid." McGucket gave another whoop and slapped Dipper on the back. He beamed, maybe he wasn't a total failure of a leader after all.

The Mystery Shack (they should've thought of a cool nickname) started shaking as it rose from the ground. Fiddleford had rigged the portal beneath the shack to be both the main power source and a high-power laser cannon. That man was the definition of a mad genius.

Apparently, the cannon had a large cooldown. Since it drained from the battery source as well, they had to make sure every shot counted. They had two or three, max.

Dipper wished he could see what this beast looked like from the ground. He could only imagine how cool the arms looked. One of the arms was just a simple claw mechanism, but the other was a literal T-Rex head. Fiddleford had also rigged his old Lochness Monster to act as tail that had the jaw strength to crush cars. That was the definition of rad.

Luckily the pyramid wasn't too far away because the Shack rocked more than a boat in a hurricane. The legs weren't exactly what you would call 'high quality'. They were rusting heavily and caused huge jerking motions. Even Mabel was looking a little green.

As they approached the pyramid, Dipper thought he'd heard a soft humming sound. It wasn't consistent, though. It stopped and started at random times and the pitch wavered. As they continued to get closer, the sound became louder and more defined. It wasn't long Dipper knew exactly what he was hearing

The scouts that they'd sent out for reconnaissance after the bonfire had reported a massive party going on. They also said they heard a sound that was muffled by the music being blasted, but there was no music anymore. All that remained was the screaming.

Bill had to be magnifying it, somehow. There was no way a human could produce those inhuman noises.

Dipper shuddered. He suddenly understood why Star did what she did, it was terrible just bearing witness.

All of a sudden it stopped. The music and the screaming; it seemed as if they'd been spotted. Dipper was actually thankful, though. The pyramid was a good hundred and fifty feet in the air and the Shack had no real method of reaching it. If Bill didn't rise to the occasion then the robot was useless. It was a big gamble that no one had really considered.

Bill shimmered into existence; his singular eye trained on them.

"Well, Would You Look At That? Someone Thinks They Can Stop Me? Hilarious!" His form erupted in laughter.

And flames. His bricks separated from each other as white flames ignited from within. Did Bill have some sort of internal anatomy? Or was he just pure weirdness? Dipper decided it may not be the best idea to ask him to find out.

"I'm A Little… Preoccupied At The Moment." Dipper couldn't breathe. He was talking about Marco. Bill shook his hand like he was rolling a pair of dice. When he opened his palm, meteorites came crashing to the ground. Out of the smoking craters came the stuff of nightmares. The henchmaniacs.

"Have Fun!" As they walked out, they grew in size. They went from the size of a regular human being to matching the size of the Mystery Shack. their features darkened as if there was a permanent shadow over their faces. The eyes started glowing red, too.

The women with the fiery hair pointed right at Dipper through the window. She grunted and yelled an incomprehensible war chant. Apparently, aliens didn't speak English, but it didn't take a rocket scientist to realize that she was the leader.

The giant beast that looked like a moldy loaf of bread charged.

"Monster! Twelve o'clock!" the multi-bear was busy relaying the message to the people who weren't near a window. Fiddleford gave a holler and started slapping at the levers and buttons, seemingly at random. It worked though as Dipper was thrown to the left as the Shack dove to the right.

The team in charge of the left arm swung in a wide arc. It was clumsy, though, and went wide. The living pair of dentures had hidden behind the Loaf. It was smaller and more agile and was able to match the Mystery Shacks juke. Its teeth landed on the left leg.

"Multi-Bear! Get the tail crew on Chompers!" one of the heads nodded and Dipper was able to watch as the lochness monster head snaked around to the undercarriage. Too busy trying to immobilize the enemy, it didn't notice the threat until it was thrown into the nearby cliffside.

"One down, five to go."

8-ball, the slouching goblin with 8-balls for eyes, was next on the menu. He ran forward and leapt in the air.

"HOLD ON!" Fiddleford threw the lever to his left and the whole Mystery Shack spun in a giant circle. 8-ball was hit by the amber coated dinosaur head like a baseball bat. Dipper and Mabel were thrown by the centrifugal force.

"Maybe a little warning next time?"

"Yessiree!" Maybe the old man was having just a little bit too much fun. Dipper sure wasn't going to stop him, though. This was his day of revenge. Those demons (mostly Bill, but that reckoning would come later) had stolen years of his sanity. Plus, he was really good at staying alive.

The loaf of stone came charging from behind and this time the Mystery Shack was grazed in the encounter.

"Hey!" Gruncle Stan yelled. "They weren't supposed to be able to touch my Mystery Shack!"

"Damage report!" Dipper yelled. A few windows had been shattered and some paint was scraped off. Nothing too bad this time, but Stan was right. Maybe the unicorn hair was specifically for Bill. Or maybe it'd stopped working entirely. They needed to be a lot more careful.

The rhombus was next, and boy was it stupid. It'd soared high in the air hoping to avoid detection. It took a dive trying to kamikaze its way through the command center. Instead it landed right in the lochness monsters' mouth. Grenda was in charge of that division and Dipper could hear her delight as she swung the poor creature around like an infant treats a toy. He almost felt sorry for it.

Almost.

The fiery demoness was lurking behind enemy lines until it was just her, the juggernaut loaf, and the Mystery Shack. Nothing they'd done had been able to stop that behemoth.

She pounced, but unlike some of the other demons, she stayed low to the ground. If the loaf was a an 18-wheeler, large and sluggish, then the fiery demon was a motorcycle, small and agile. She was never in the same spot for more than a second, constantly moving around the playing field.

The Shack tried to kick her but she dodged to the left. She was able to rake her fire tipped nails against the legs armor. Luckily there was a billboard covering the kneecaps. She laughed in delight as the paint sizzled from the heat.

"she's a tricky one, bro bro." Mabel was right, they weren't coordinated enough to defeat her. She was just too fast. The Loaf was charging at them again. Instead of dodging it, Fiddleford had the Shack stand its ground. They braced for impact and were still thrown from their positions. That thing was just an unstoppable force.

The gang was just able to hold it together. They were still losing ground, though.

Dipper turned to McGucket to yell at him to do something, but the old man was staring intently out the window. He was mumbling quietly to himself. Something must've happened outside because he suddenly slammed on a blue button behind him.

A distinct humming permeated his friend's anxious screams. It sounded like a UFO in those corny horror movies he used to watch with Wendy.

An explosion emanated from below Dipper as a high-pitched whirring sound clawed at his eardrums. He looked out the window and was immediately blinded by the blazing azure laser beam. Dipper screamed in surprise. His felt as if the laser had permanently imprinted itself on his retinas.

"What the heck was that!" Dipper may not have used those exact words, but he was too stunned to notice.

"That there was a weaponized teleporter. I just done vaporized our enemies, Yeee Haww!"

Enemies? Dipper took another look out the window as his vision cleared up and saw that the gray loaf of evil had a giant cylinder taken from the middle. It was slumped to one side and a viscous green liquid was oozing out.

Beyond that, however, was an even more surprising shot. The fiery demoness had been caught in the attack. She was missing her entire torso and lay unmoving in the ground. That crazy old man had lined up the shot to take two birds with one stone, or two monsters with one weaponized portal.

"Wow, great shot, but maybe a little warn-"

"WHAT WAS THAT?!" Bill materialized in front of them. His body shook in rage as he saw the slaughtered henchmaniacs. His body momentarily blurred out of focus. It looked like he was having trouble containing his pyramidal form.

"I'm Going To Make You Eat Each Other's Inner Organs For That!" He grew to the size of a skyscraper and slammed his fists into the Mystery Shack. Dipper flinched as the world darkened. This was it, no one could say they didn't at least try to stop Bill.

The ground shook and the trees swayed intensely from the shockwaves of the impact, but when the dust cleared, the Shack was still standing. An opaque shield filled with strange hieroglyphs surrounded them before melting away. The unicorn hair forcefield worked!

Dipper and Mabel cried out in joy among the others. Bill was not pleased. He shrunk back down to match the jerry-rigged robot that had somehow managed to survive a force that could've wiped out the dinosaurs.

"WHAT?! YOU THINK THIS WILL STOP ME?!" Bill's body turned red and his eye turned into a black vortex, talk about wearing your emotions. He got into their faces as he threw insult after insult, he also threw punches that reflected off the force-field.

"Get ready everyone, this is it! Etraction team, to your stations!" Dipper yelled over the 1MC. The tubes in the main command room opened and they all clambered inside. As Bill got particularly close, the dinosaur arm launched into action. It grabbed Bill's eye and yanked it out.

His scream was bloodcurdling.

"DO YOU HAVE ANY IDEA HOW MUCH ENERGY GOES INTO MAKING A NEW EYE!" Blinded by fury and, well, blindness, Bill didn't notice the group launched out of the totem pole cannon as the Shack started its offense.

The wind howled in Dippers ear as they arced through the sky. They pulled open their parachutes at the last second and tumbled into the triangular hole in the side of the pyramid. Dippers shoulders hurt from the parachute yanking him out of his decent, but he'd rather be sore than dead. Besides, everything was going a lot better than he expected.

Considering Dipper had expected to be obliterated by Bill without a second glance, it wasn't too much of an achievement and they still had a long way to go before the day was over. He glanced back through the window and his jaw dropped.

Bill was pinned underneath the mystery shack! Could they stop him here? The demon was throwing punch after punch, but nothing was getting through!

…Until he aimed for the legs. Dipper and the others watched in horror as Bill ripped them apart. He stood victorious over the Mystery Shack.

"I May Not Be Able To Get In There Yet! But That Force Field Will Break Eventually And You Guys Will Run Out Of Food Soon!" Since his target was now immobile, Bill grew extra appendages and started to rain blows down on the mystery shack.

Dipper could only stand there and watch as cracks started to appear on the force field.

AN: Wow, that was more than double the length of some of my previous chapters! I hope you guys enjoyed it. I realized that a thousand words per chapter is actually pretty short so I'm going to try and keep up with the new length if you guys want. Also, this story passed 20k words! I know there are tons of stories with more, but I'm pretty proud of myself.
