Just real quick, I put in a new font for Bills voice, so when he is speaking, there will be a cool horror style font. Enjoy!-

Bill walked out of the room, laughing hysterically. He heard what Dipper said and couldn't hold in his laughter. It was just too funny!

"Whelp, time to head downstairs." Bill said, falling down the stairs.
Bill landed with a big thud at the bottom of the steps, causing Mable to rush in, seeing her 'brother' laughing insanely. She just stood there, looking at her 'brother', fear and pain crossing her eyes.

"D-Dipper?" Mable asked hesitantly.

"Yes, my dear sister of mine." Bill said, staggering to his feet."J-just wondering if you were okay. You had a nasty fall there." Mable said, awkwardly rubbing the back of her head.

"Why, I have never felt better. It's good to be on two feet, ya know?" Bill commented.

Mable backed away from 'Dipper'. Why, of all people, would 'Dipper' act like this, was all Mable could think of. It just didn't make any sense to her what so ever. Mable looked at 'Dipper' for half a second more, before leaving the room in a hurried walk. During all of this, Dipper floated above them, watching in horror and disgust at what he had witnessed. Of course Bill could see him, floating like a stray balloon on the wall, so why not enjoy the moment? Dipper suddenly had a rush of anger and guilt go through him. Before he knew it, he was face to face with himself, arguing with the former triangular demon.

"What was that about Bill?!" Dipper yelled, balling his hands into fists.

"Why, that was me just, testing out my new vessel." Bill said, looking at his nails like some high school cheerleader.

"Don't talk about my body like it is just some, automobile that you can use whenever you want!" Dipper was now scorching with anger.

"But pine tree, its mine now, and I can do WHATEVER I want with it, and there's nothing you can do about it." Bill said, walking to the kitchen.

"Where are you going?"

"To test out the durability of these arms of course. Want to see if you kept them in good shape." Bill said, opening the utensil cabinet.

Bill grabbed out possibly the sharpest fork in history. Then, as quickly as he found it, he started to jab it into his arm, making puncture wholes throughout his arms. Dipper could almost feel the pain of the fork, puncturing his skin. How Dipper wished he would just stop. Soon, Bill stopped his little stab-fest and cleaned the fork off, grabbing for something even sharper. Once found, he headed for outside. Outside, he sat down on one of the steps, looking down at the object he was holding. Dipper could only imagine what he would do.

"Now for the legs!" Bill exclaimed.
