Mystery Shack deed

The  is the deed to the Mystery Shack, which was stolen by Gideon Gleeful in "Dreamscaperers."

History
Far before the events of "Dreamscaperers," Stan Pines placed the deed of the Shack inside the safe in his office.

Afterwards, the deed is seen again in "Dreamscaperers" when Gideon tries to steal it from the safe in Stan's office. Stan stops him, places the deed in back in the safe, and locks it. This forces Gideon to summons Bill Cipher which he then commands to go inside Stan's mind to find the memory of him imputing the combination to the safe. After hearing this, Mabel, Dipper, and Soos band together in order to stop Bill. When Gideon witnesses Bill's failure he has no choice to resort to "plan B," dynamite, which he uses to break into the safe and steal the deed.
