The episode opens where the last one left off.

"Yaaahh!" Yelled Aaron, Kate, Claudette, Saul, Dr. Jack, Mr. Jones, Brian, and Erik yelled as they came through the door.

We then see a group of leprechauns, Sebastian, Carlos, both Lilly's, Erik, Garth, Jack Frost, Santa and some of his elves, Dr. Sawbones, Ricardo, and Humphrey's mom. They yelled as they came through the door.

"Yaaaahhhh!"

"Wait. Sebastian! (Run to him)"

"Kids! I can't believe it! I thought I lost you two!"

"So... what's everyone doing here?"

"It's...it's a long story." Said Dr. Sawbones.

Sebastian lights a match and throws it into a can, illuminating the shack, revealing the people sitting around the room.

"Welcome to what's left of normal around here. Home base." The screen pans across the various people hiding in the Mystery Shack.

"Ah! The leprechauns?" Aaron asked.

"Do not be afraid laddy. We won't steal anything from you… we have learned that the economy failed so stealing is pretty much pointless as everyone does it."

"Can someone tell me why this house is free from the nightmare out there?" Saul asked.

"I think that they think we're not in here." Dr. Sawbones explained.

"It's because of the spell that Wayne put on the house!" Saul said.

"Then these people needed a place to stay and since the mayor got captured, I elected myself de facto chief. The plans to stay in here and eat Brown Meat until we run out." Sebastian said.

"Sebastian, we can't all just hide inside. There's a town in need of saving. Me and Wayne tried to do it, but he got captured by the Devil."

Saul then climbs on top of the TV. "Guys, don't you see? Our friends need us, but we can only save them if we fight back." Pulls Claudette up after him.

"Saul's right. Satan wants us to run and hide. He wants us to think he's invincible. But Wayne, before he was captured, knows the Devil's secret weakness."

The refugees perk up and start muttering.

"Weakness?" Ricardo asked.

"Now, if we band together, if we combine all of our strength, our smarts, our...whatever Erik over there has..."

Erik then shouted. "Various rashes!"

"...then we just might be able to rescue Ford, learn Bill's weakness, and save Gravity Falls!"

Everyone cheers as music starts to play and Aaron then started to sing.

Aaron:

When the Devil has screwed you,

And made you fear death

When you've been scared, tortured and been made like a fool,

And he's taken your last breath.

There's been one thing that can be done,

You can get up and fight.

Don't just sit and take it,

Keep the Falls alive!

You do it for you and me

And help us save a fair city

Answer all the calls

And break down the fourth wall

And say that you'll won't surrender and would die

Just to keep the falls alive!

Humphrey's mon:

Tired of him bullying you?

Everyone:

Keep the falls alive!

Dr. Sawbones:

Tired of always being doomed?

Everyone:

Keep the falls alive!

Saul:

Want to see us win?

Everyone:

Keep the falls alive!

Claudette:

Don't want him to be king?

Everyone:

Keep the falls alive!

You do it for you and me

And help us save a fair city

Answer all the calls

And break down the fourth wall

And say that you'll won't surrender and would die

Just to keep the falls alive!

Aaron:

If you're feeling angry, yell it out!

Everyone:

Monsters in your business!

Keep the falls alive!

They're giving you all this mischief!

Keep the falls alive!

Won't take crap from the antagonist!

Keep the falls alive!

Everything he tries to do

Makes you look like a fool

Change the script and change it up

This is our show now because

He wants us all to surrender and die

Keep the falls alive

Ricardo:

When the Devil has screwed you,

And made you fear death

When you've been scared, tortured and been made like a fool,

And he's taken your last breath.

There's been one thing that can be done,

You can get up and fight.

Don't just sit and take it,

Keep the Falls alive!

Everyone:

Go to war, make a scene

Do this for you and me

And show 'em what resistance means.

Why march in someone else's caravan

Especially when they're the guardian of the dammed!

It's time to throw some shit against a fan!

Aaron:

There's no way you can stop,

MERCY…. FALLLLLSSSSSSSSS!

Everyone:
Keep the falls alive!
