"Mabel hurry up! We're going to be late!" Dipper called to his sister, trying to keep the gigantic backpack he had from falling to the ground.

"I'm coming Dipper! I just need to find my camera!" Mabel responded.

"You can get a camera there!" Dipper sighed and took off the backpack. He began pacing back and forth trying to calculate exactly when the bus would arrive.

Dipper was wearing his regular attire. An orange tee shirt, dark blue vest, grey shorts, black shoes, and a blue hat with a pine tree design.

Dipper had got the hat at a nearby convenience store. For some reason he didn't feel right without one, but he still had Wendy's hat tucked away in his backpack.

Dipper's brown hair had a slight curl to it by not much. Most of it was stuffed under his hat or covering his Little Dipper birthmark.

Mabel finally ran down the stairs with her own bag, which was somehow smaller than Dipper's.

Mabel, being Dipper's twin, was very similar to him. She had the same color hair, most of it just went down her back.

She had a pink headband in her hair. She smiled eccentrically, showing off her braces. Her cheeks had a light blush to them Mabel was wearing her shooting star sweater, purple skirt, and black shoes.

"Mabel, it'll be a miracle if we don't miss the bus now." Dipper said, hauling his backpack up onto his shoulders.

"Oh don't worry dip. Besides if I didn't have my camera how could I save all the memories. Click!" Mabel held up the camera and snapped a picture of her brother.

"Let's just hurry before we're late. We're already lucky enough that mom and dad are letting us spend another summer in Gravity Falls." Dipper moved to the door and shivered. "Did it just suddenly get really cold?"

"Nope!" Mabel replied, she opened the door and a blast of cold hit them. Snow was piled up outside their door, more snow was falling from the sky gently.

"Wh- is that snow!?" Dipper asked in shock.

"Yay snow!" Mabel dropped her bag and ran outside, rolling around in the snow.

"This is impossible. Isn't it? Alright we're going to Gravity Falls. I'm sure Ford can help figure this out." Dipper reasoned with himself. He was jarred back into reality when he heard his sister scream.

Mabel ran inside and shut the door, her face as pale as a ghost. "B-b-b-b-"

"Mabel what's out there?" Dipper asked.

"Bill!" She shouted, the door burst open and five triangular men similar to Will came in. The only differences were their bow ties weren't spinning and their bodies were made up of purple.

"We're not Bill. We are the Williams." They said in unison. "We serve Will Cipher. And his orders are to capture everyone we se-" While they were talking Dipper had dug out the heaviest book he had in his bag, an encyclopedia, and threw it at them.

Dipper and Mabel ran past them into the cold, one of the Williams ordered the others to seize them.

"We need to find a way out of here!" A laser soared over their heads and exploded in front of them. The twins turned to see all five Williams had recovered and were hot on their tails.

"We have you now!" The Williams all laughed and appeared to smile with their eyes. Just then a paintball struck the clear leader in the eye. He fell backwards, writhing in pain, soon followed by the others.

"Dudes over here!" A familiar voice called. Dipper and Mabel turned to see their friend Soos riding a snow machine. Soos was wearing a parka and goggles.

"Soos! How did you find us?" Dipper asked as they ran over.

"I used the address from all the letters we sent each other. Look I don't know what's up with the snow but Mr. Pines's brother knows and he told me to get you dudes." Soos explained.

"We're gonna see Gruncle Stan and Gruncle Ford! This'll be great!" Mabel cheered as they climbed into the machine.

"Alright dudes, hang on!" Soos warned and the machine sped forward towards Gravity Falls.

After a few hours the finally arrived at Gravity Falls. The snow began to be less common until they had to leave the machine since there wasn't any snow left.

They walked up onto the cliff to get a good look over Gravity Falls. Everything seemed to still be normal. Nothing was burning and there wasn't even any snow.

"How is this possible? I can see snow over there but everything is fine here in Gravity Falls." Dipper said.

"Probably some voodoo magic or something." Soos suggested.

"Whatever the case, the good news is Gravity Falls is ok!" Mabel said.

"Yeah but what about our home? What about mom and dad?" Dipper gasped. "What about our stuff? Wendy is going to kill me!"

"Oh relax Dipper. I'm sure it'll be fine. You have the excuse of evil purple triangle guys trying to enslave you." Mabel reminded him.

"That reminds me, what was up with those William guys?" Dipper wondered.

"They said they worked for a guy named Will Cipher." Mabel remembered.

"Cipher? Wasn't that the name of that other triangle dude, Bill?" Soos said.

Dipper began pacing. "I have a bad feeling about this. If this Will Cipher is related to Bill Cipher, then we have a big problem." Dipper took out a pen and began clicking it.

"Kids!" Two thankfully familiar voices called, Dipper, Mabel, and Soos turned to see Stanford and Stanley Pines running up to them.

Stan was wearing his black suit he wore when trying to scam tourists into buying useless junk. His red fez covered his grey hair. Stan was also wearing glasses and had a lot of grey stubble on his face.

Ford was wearing a red sweater, black pants, grey boots, and a brown coat. His glasses had a crack and he had very little stubble. His grey hair was short for the most part.

"Gruncle Ford! Gruncle Stan!" They yelled and ran up to embrace the brothers. The Pines family hugged, and then Soos joined the hug making things awkward.

Soos had removed his parka and goggles revealing he was in his old green question mark shirt, brown hat, and brown shorts.

"Thank goodness you're alright! I was sure that green devil's slaves had gotten you!" Ford said.

"They almost did, but Soos came in and saved us." Dipper said.

"Man I've missed you knuckleheads!" Stan said.

"We've missed you too Gruncle Stan." Mabel said.

"Unfortunately we must save our catching up for later. Soon the entire world will be plunged into Oddmageden by Bill's older and much stronger brother Will. Back when me and Bill weren't enemies he briefly mentioned Will and how he'd tried to destroy Will but was overpowered. Fortunately for him Will's enemies sealed him into another realm. It appears the seal has been broken and Will is slowly regaining power." Ford explained.

"Did Bill mention any weaknesses?" Dipper asked.

Ford nodded. "Indeed. He has a weakness similar to Bill's, there is a Zodiac that can destroy Will. I know you two are a part of it but I'm not sure who else. I have a picture of the Zodiac in the basement. So we must hurry there."

"Wait wait wait. So if Will ways able to attack California then why isn't the rest of the world under attack? And why California?" Mabel asked.

"Well like I said before, he's slowly regaining power and isn't strong enough for worldwide domination yet. And I'm assuming he targeted California because you two are part of the Zodiac I defeat him. Fortunately I used what remained from when we Bill-proofed the shack to Will-proof Gravity Falls."

"Alright then. Let's go to the Mystery Shack! I swear Soos if you did anything to it..." Stan let the threat hang in the air, Soos didn't reply. Just then the Earth began to shake so forcefully that the Pines family and Soos were thrown off the cliff, falling to the ground.
