EyeGnome began to laugh as energy swelled through him. "Yes! YES! You LOSE Ford Pines!" Energy surged around EyeGnome's allies. Gremoblicorn's eyes began to glow and he vanished. Screams of terror began to flood from outside.

Ford turned around to see massive holes had been blown into the cave and he could now see the sky. The sky was a mix of a rainbow of colors, giant unfamiliar beasts flew by and giant snakes slithered through the air.

"Time Zombie, go take care of the two children. As long as they have time travel on their side, they're a threat." EyeGnome ordered. The zombie nodded and he vanished.

"What did you do?" Ford demanded.

EyeGnome began to laugh. "I've fused the multiverse, Ford! All into one pocket of chaos! The Earth will collapse under this apocalypse and you'll watch everything burn!"

Jeff and the Gnomes gathered together and EyeGnome turned to them. "Gnomes, go enjoy your new power and wreak havoc." The Gnomes all grinned and rushed out into the woods towards the town.

EyeGnome turned to face Ford with a toothy grin. "As for you, Dark One. Prepare to die by our hands!"

Dipper and Mabel tried to run from the ogre but it slammed its club in front of them again. "Kids, look out!" Stan told them, they instinctively ducked and an explosion sounded above them.

They looked up to see the ogre groaning it fell backward and Dipper and Mabel ran to Stan. "Good thing I know where my brother keeps his weird tech stuff. What's happening?" Stan wondered, looking up.

"I don't know, but if I had to guess, great uncle Ford wasn't able to stop those crazy fusion guys." Dipper speculated. Then his eyes widened. "Oh no. There's nothing keeping them in, this isn't like Bill. They can escape Gravity Falls."

Mabel began to panic. "But then... what about mom and dad?"

Stan quickly picked the kids up and went into the house before taking a deep breath.

"Great uncle Stan, what are you doing?" Mabel asked.

Stan began to pace. "This place should still be safe, right? It better be. We need to get Ford back. But..." Suddenly a chair with a face jumped through the window, it began to scream and Stan tossed it back out. "Ok, so it isn't safe. This is fine. This is fine."

Dipper and Mabel looked at each other. "Great uncle Stan!" They shouted in unison and he looked down at them.

"I know where gruncle Ford is, I saw the location of their base too. And we can't just leave everyone in this chaos. We have to fight back against this." Mabel argued. Stan opened his mouth to protest. "What other choice do we have?" Mabel asked him.

"You kids are going to go either way," Stan said. "At least this way somebody who knows what they're doing can keep you two safe," Stan said as if he was trying to convince himself.

"Alright!" Dipper pumped his fist into the air. "We need to gather as much gear as we can and hurry over to town," Dipper said and he ran upstairs. He grabbed his height-altering flashlight and journals while Mabel grabbed attack glitter and grappling hook. The twins ran downstairs to meet their great uncle.

Stan sighed. "I hate this. If you kids die this is NOT my fault." He said, and the pines twins set out into the wasteland.

The family quickly arrived in town to see that everything was falling apart. Strange creatures were attacking the townsfolk. Massive bird creatures swooped down to try and grab some of the townspeople.

One bird grabbed hold of Soos and began hoisting him into the air. "Ahh! Help!" Mabel whipped out her grappling hook and fired it into the bird's face. It dropped him and flew away.

Soos stood up, wincing. "Thanks, guys. What's going on here? This is like, way out of wack."

Stan shrugged. "Something happened with my brother, and now we're trying to track him down."

Dipper looked at the struggling townsfolk. "We have to help them." He said.

"You're right, and I know just how to do it," Stan told them and he whistled to get everyone's attention. "Everyone! You need to fight back, just like I've taught you! It's time to defend your home!"

Something seemed to click with the people of Gravity Falls, they began fighting back against the attacking monsters. Tyler picked up and sign and swung it into one of the strange beasts and then Manly Dan punched him away.

"Wow! How did you get them all fighting?" Mabel asked.

Stan grinned. "I gave them a crash course in handling all this weirdness back when that weird bull monster attacked. I know a thing or two about learning how to fight quick."

Wendy ran up to the family, ducking under an attack from a flying snake. "Guys! Why is there an apocalypse whenever summer ends?"

"I'm starting to think we're cursed or something." Mabel mused.

"Well now that we're all together, let's go find Ford," Stan said, as he turned to leave the Gnome army arrived with Jeff in the center of the pack.

Jeff began to laugh and fired energy from his hands into the Gnomes, duplicating them over and over. "We will finally have our queen! All hundreds of us!" Every single Gnome looked right at Mabel.

"Oh boy." Stan groaned, suddenly a grenade landed in the Gnome cluster and exploded.

Rick ran in guns blazing, laughing like a madman as he fired at the Gnomes. "Take this you little gremlins! AHAHAHAHA!" The Gnomes scattered and Rick turned his attention to the group. "Alright, where's Ford. I want to know why I'm here instead of in the Mermaid dimension."

"We don't know any more than you, he went to go stop his old experiments earlier today and we haven't seen him since. We're trying to get to the base now." Dipper explained.

Rick groaned when his portal gun failed to open a portal. "Every single dimension has been fused together. Looks like I have help clean up this mess Ford's made. Where's their base?"

"Somewhere in the woods to the north, I don't know for sure," Mabel told him.

Rick was about to say something when the Gnomes reemerged as one colossal gnome beast, Jeff was on top firing magic down at the ground.

Stan took a deep breath and looked down at the twins. "Look you two, we'll handle this. Just run. Don't try and save Ford alone, but get out of here."

Dipper and Mabel looked up at him. "B-but great uncle Stan." Mabel whimpered.

"Just go!" Stan said and the twins darted into the woods as the rest of the group began fighting the Gnome monster.

Commercial.

Multitaur put his many hands together and flexed his muscles. "Do I get to destroy them?"

EyeGnome nodded. "Yes, rip them to pieces Multitaur!"

Multitaur charged at Archer and Ford, the two separated and let the fusion run into a wall. "Now we have to deal with the big guy." Archer sighed and began shooting arrows at Multitaur that exploded on contact.

"Ugh! Stop running and fight me!" Multitaur shouted and he rushed at Archer, grabbing for the man.

Archer jumped back and punched Multitaur in the face, the beast ignored his attack and grabbed him, then threw him into the wall.

Ford jumped in between Archer and Multitaur and tried punching the fusion.

"Ford, what are you doing?" Archer demanded. "This isn't working, when will you learn?"

Ford ducked under Multitaur's one arm. "It doesn't matter, you're family Archer, and I'm going to help you. Because that's what family does!" His fists didn't seem to affect the creature at all. He took out one of his weapons but Multitaur threw him aside.

Multitaur stomped over to Ford with a wide grin and raised his foot to crush him.

Dipper and Mabel stopped running once they were decently far from the town, the twins took a moment to catch their breath in the chaos. "Alright, we have to find great uncle Ford," Dipper said.

Mabel nodded but before they could proceed a cool breeze blew through the woods. The twins looked around and suddenly laughter emerged from all sides of the woods.

"Ah good, you're alone." Time Zombie said, appearing behind the twins.

Dipper and Mabel took a step back as the zombie loomed over them. "Stay back!" Dipper ordered.

Time Zombie chuckled. "You think I'm scared of you? Let me show you just who you're dealing with!" He ran at Dipper, who blocked the zombie with his robot arm. Suddenly they vanished in a flash of light and reappeared in an empty field.

"What in the?" Time Zombie seemed surprised and Dipper took the opportunity to punch him in the face. Time Zombie's jaw went flying off of his face but it quickly returned to its place and the zombie charged at Dipper. They collided again and vanished.

This time they reappeared in moving traffic. Dipper knocked Time Zombie away and raced off of the road, Time Zombie was run over by a moving car and Dipper caught his breath. "Wait a minute, are we... time traveling?" He looked down at his robot arm. "That's right! Ford put a time travel device into this thing! I should be able to control it then." Dipper concentrated and vanished.

Dipper appeared in the Mystery Shack behind a shelf "Hm. I think I'm a bit too far in the past." Suddenly Time Zombie jumped out at him and moved to bite him. "Agh!"

Dipper was knocked back into the shelf and a souvenir was knocked off of the shelf, and made a crash sound.

"Ow!" Past Dipper said, suddenly future Dipper felt a new bruise on the back of his head.

Time Zombie and Dipper vanished again and reappeared in the woods.

"See! I can alter time itself now! You cannot win!" Time Zombie said. Dipper kicked him in the stomach and his arm began punching Time Zombie on its own over and over, once he was knocked down Dipper noticed how hot the arm had gotten and traveled back to the present.

Dipper concentrated and went back to the present where Mabel tackled him in a hug. "Dipper! What happened?"

"I was time traveling while fighting him, this robot arm is crazy but I think I'm overloading it," Dipper explained. "No matter what I do I can't seem to stop him. He just keeps regenerating and following me through time."

"Wait a minute, if we can time travel, I know just how to stop him!" Mabel said.

Commercial.

Rick and Stan fought back to back, fighting off attacking Gnomes one by one. "Ugh! There are too many of these stupid things!" Stan complained.

Rick kicked one off of his shin. "How do we stop them?"

Stan looked around and focused on Jeff. "I'm pretty sure he's the leader, if we stop him, it just might stop the rest of them."

Rick nodded and he suddenly rushed through the crowd of Gnomes and began firing at Jeff, he pulled out the pin of a grenade and tossed it in Jeff's direction. It exploded and knocked Jeff off of his feet.

Stan rushed over to where Jeff landed and picked him up. "Listen up you little pest, get you and your Gnome army out of here and I won't turn you into a beachball." Stan threatened.

Jeff put his hands in front of his face. "Alright alright! I'll do it, just don't hurt the merchandise! Retreat!" He yelled, the Gnomes then all ran back into the woods. Jeff slipped out of Stan's grasp and ran into the woods as well.

Fiddleford ran to join Soos, Stan, Wendy, and Rick. "Hang on, are y'all looking for Ford?"

Stan nodded. "Do you have any idea where he is?

Fiddleford shook his head. "Sorry, no clue. But I want to help y'all fight whatever's causing all of this.

"Perfect, the more the merrier. Now, let's go find Ford," Rick said.

Multitaur raised his foot over Ford to crush him. Ford tried to move but wasn't able to get his arm over him. Archer suddenly fired an arrow at Multitaur, it expanded and formed a net that began to electrocute Multitaur.

Archer ran behind Multitaur and threw his bowstring around the fusion's neck, pulling back until the monster passed out.

"Archer, thank you," Ford said, accepting Archer's hand to help him up.

Archer nodded. "You know Ford, you've thrown yourself into danger to help me multiple times today. And I think I get it, seeing family in danger like that... it just triggers something in you. I'm sorry I didn't realize that before."

Ford smiled at him. "That doesn't matter, you understand now Archer."

"One more thing Ford," Archer said. "Call me Shermy." The uncle and nephew smiled at each other and embraced, then they turned to face EyeGnome, who had a look of disgust on his face.

EyeGnome placed his hands on the orb. "You dare do this in front of me? I will have you torn apart ATOM BY ATOM!" The entire room began to glow and the ground began to shake.

Dipper and Mabel traveled in time to the night they fought off a zombie army, they crouched behind a rock near the Mystery Shack and went over the plan.

Time Zombie appeared near them and began to laugh. "You fools don't get it, do you? I CONTROL time now! I have no limits, no rules!" He snapped his fingers and all the zombies suddenly turned their attention to future Dipper and Mabel while past Dipper and Mabel prepared their song performance with past Stan.

Mabel shot her grappling hook into a tree and it pulled them both onto the branches and Dipper shrunk down some of the zombies getting too close. "Alright Mabel, on my count," Dipper said, looking over at the Mystery Shack. "One, two, three, now!"

Mabel fired the grappling hook and it hit Time Zombie, it began to pull him in just as past Stan, Dipper, and Mabel sang their first cord, obliterating Time Zombie in midair.

Future Dipper and Mabel quickly jumped back to the present and sat down in the woods to take a breather. Dipper looked down at his arm and noticed that the metal arm was sparking and smoking, suddenly it broke into two pieces, revealing Dipper's pale healed arm.

"Aw man, I guess it couldn't handle all that." Dipper sighed.

Mabel booped Dipper's hand and smiled. "At least your hand is healed."

Dipper wiggled his fingers and nodded. "Yeah, now we need to find where great uncle Ford is." Suddenly a beacon of red light exploded into the sky not too far from them. "I think I have a good idea of where to look." The Pines twins ran off towards the light.

End Credits.

Somewhere in Gravity Falls, a weakened Axolotl struggled to get back up, trying to manage all of the strange interdimensional creatures constantly attacking him. "Agh! Those Pines better hurry, I cannot hold back the collapse of everything much longer. There is simply too much power in one region..." He said, firing a giant ray from his eyes that evaporated the nearest monsters.

He surveyed the extensive rebellion being performed by the townsfolk of Gravity Falls. "I am impressed by how well they are fighting off these creatures. It's beyond me how they're still alive, but I do hope it stays that way."
