Mabel decides to use a different spell to beat the Impossibeast and beat Probabilitor

In hindsight, with how things always took a turn for the strange in his life, he should've expected that a trip to promote his game would end up with him in a town somewhere deep in Oregon, and dealing with supernatural threats. Both new ones, and ones he was deeply familiar with. But whatever games those in the shadows expected him to play, he'd win them all. It's time to duel!

Bill watched this place and the people in it for awhile now thanks those strange items of theirs, especially a certain spikey, tri-coloured haired pharaoh. Figuring the brat could be useful for his plans, he decides to make a deal with the kid while he is inside of his tomb.

It's the musical one shot NO ONE will ever know about! Bandit Keith and Mabel Pines sing songs! "Yu-Gi-Oh" Abridged and Gravity Falls will never be the same! (LIES! They don't interact.) Shut up. It's funny (He thinks so, I don't), and it's original! (Originally bad.) Read, review, and be brutally honest! Have an excellent day! (By the way, this is MEANT to be bad.)
