The other puppet

The deal

This takes place in sock opera

"Tick Tock kid,"  Bill said holding out his hand.  Dipper looked at the puppets and then at the laptop.

"Fine"  Dipper said.  "But you can only have one, and it has to be in this house."  Dipper reached out his hand.  He engulfed it in the cool blue flames and shook it.  Immediately he felt something binding in him.  He gasped.

"So what puppet do you want anyway," Dipper said uncomfortably.

"Come and see" Bill cackled gleefully.  Thinking that he might have made a mistake Dipper followed.  As soon as he got down the stairs and caught up with Bill, he gasped as Mabel suddenly collapsed.  He ran over to help her up but stumbled back as he saw a horrible sight.

Her eyes......

They were yellow, well, like Bills.  Mabel....Bill?  Mabill threw his head back and laughed.  "Man, its been so long since I've inhabited a human body.  I'd love to test it out, but first thing first."  He ran up the stairs, banging into the walls and tripping along the way

As soon as Dipper got over his shock, he followed.  He ran up the stairs, praying that this was just a bad dream, that he had not just subjected his sister and best friend to demonic possession.  He got up to the attic just in time to see the laptop crushed.  He lept to it, to see if it could be saved

"Not another step,"  Mabill said holding a knife to his throat. "Not another step or your sister dies"
