Ok before we get started I better explain. So I just randomly decided one day I should do a collab book with my friend and this is the end result. The next chapter will hopefully go up next week on billmurray258 profile so go check them out to get the next chapter of the story. The simplest way to put this story is. Amazingness. Now to begin.
Dippers POV

I was running through the never ending castle with Mabel when we suddenly reached an end.

"Oh no a dead end!" I shouted but Mabel just looked it me and said

"Like grunckle Stan said. When on door closes bash the nearest wall in with brute force!" Mabel shouted and she grabbed my flashlight making her hand grow huge. She then punched the wall smashing it and leaving an opening.

"Ok let's gather everyone from gravity falls and fight back." I suggested, I then noticed bills henchmen had already captured all the townspeople. Suddenly Bill snuck up on us in his nightmarish form and grabbed us. Mabel looked at me and we were taken back to grunckle stan and grunckle ford. I struggled to break free when Bill began taunting ford demanding to get the equation for worldwide weirdmaggedden. He opened up a portal.

"I think I'll drop one into here, who knows where they'll land." Bill said

"Ok stop I'll tell you the equation!" Ford shouted

"Good!" Bill shouted and then he suddenly threw his hands up in joy throwing us both into the portal.
"Whoops butterfingers," bill realized he'd lost his blackmail and sent zanthar to go retrieve the kids, wherever they were.
"Don't worry fordsie I'll have those kids back to you in no time." Bill said nervously
