Mabel is in her bubble prison, and of course Dipper, Wendy, and Soos try to save her, but Bill gets there before them.

ON PERMANENT HOLD Mabel is dared to summon a demon, but what happens when one really shows up? I do not own Gravity Falls or any of its characters (unfortunately).

Bill Cipher has made a deal with a mysterious man where he must get a human girl to fall for him in a week. Easy! Human girls are dumb anyway, right? Little did he know, this deal would change his life forever.
