Just West Of Weird (Gravity Falls/Supernatural)

Title: Just West of Weird

This is a Supernatural (SPN) / Gravity Falls (GF) Crossover

Synopsis:
"A fiddle of gold against your soul says I'm better than you."

-the kid has got a darkside
best believe it
push too far you'll see
the kid has got a darkside
back against the wall-

Sam and Dean Winchester arrive in Gravity Falls, only to be greeted by mystery, a tourist trap, and monsters they've never seen.
With heaven and hell breathing down their necks after starting the apocalypse, they quickly try to resolve a mess that picks up steam, threatening their new crew: the Pines family.
But Bill Cipher, a dream demon set on his ways watches from the shadows, grinning all the while.
"The Winchesters? And the Pines? All in one place?" He rubs his hands together excitedly, single eye glowing bright, voice dropping, getting deeper, a cavernous void to swallow them whole. "Why, Luci, you shouldn't have."

-la la la la la-

Dipper and Mabel Pines are fated to leave their beloved summer shack by request of their parents when two friendly visitors roll up, saying something about 'hunting' and 'saving people', the 'family business'.
Before they can get a grip, strange new threats pop up to deter them, getting darker and stronger, meaner, less forgiving.
With the Winchester's help the two families stick together to push back against Lucifer and his horde that strive to end their existence, sweating, bleeding, and praying with all they have in them.
But the question is, can they do it?

-the kid has got a darkside
best believe it's the
last trick up his sleeve
the kid has got a darkside
that you don't wanna meet at all-

"Did you miss me? Admit it, you missed me."
