Your siblings Dipper and Mabel were out solving mysteries so you took the chance to explore gravity falls forest. You enter a cave and the entrance suddenly begins to collapse trapping you inside. You turn to find a giant monster staring down at you before attacking you. Suddenly you see Bill appear next to you, his yellow hair and eyes turning red as he grows another set of arms and mouth. He looks pissed as hell glaring down at the monster, a murderous look on his face. "Just stay there."
