So... Sorry I have been slow on updating. Too much homework. By the way, I don't own gravity falls... Just wanted to let you know that if you didn't know already.
Dipper's POV:
"Hey, Stan? Have you seen mabel? I saw her take waddles for a walk three hours ago, but I haven't seen her since." I yelled from my room.
"No. But waddles just came in here.
You might want to come down here." Stan yelled back.
What? Waddles? Without mabel? I ran downstairs to find waddles frantically pushing Stan towards the door.
"Waddles, what is it? Where's mabel?" I said.
"Oink oink oink oink!"
"What? You know I can't understand you when you talk like that!" I said.
"But I'm sure you can understand me perfectly, pine tree." Bill said behind me.
Soos, Wendy, Stan, and I turned around and backed up.
"AAAAAAHHHHHH!" Stan, Soos, and I screamed.
Wendy looked confused.
"Who's the yellow triangle guy?" She said quietly.
"Bill Cipher; Dream demon, kidnapper, and deal maker. Nice to finally meet you, ice bag." He said, shaking Wendy's hand.
"Umm... Guys? Why did you scream?" Wendy asked.
"Because dude, he's evil!" Soos said.
I walked over to her.
"Wendy, whatever you do, do NOT make a deal with this guy."
"C'mon pine tree. I'm not that bad. I mean, sure I tried to kill you and I kidnapped your sister..."
"WHAT?" Stan yelled.
Bill backed against a wall as Stan glared at him.
"Bill, where is mabel?" Stan said in a dangerously calm tone.
"Haha... Funny you should mention that..." Bill squeaked nervously.
"WHERE IS SHE?" Stan yelled.
"I'll tell you where she is if you make a deal with me." Bill replied, suddenly more confident.
"Never!" I yelled.
"Hmm... You know what, I think I'll just hold you all hostage instead. Except for ice bag and question mark. As annoying as they are, they aren't pines." Bill said as he snapped his fingers and the pines poofed to the dreamscape.
