The lever activated.


The tree used to enter the bunker is located in the Gravity Falls forest. The bunker can be reached by pulling a lever disguised as a branch, which opens a hole with stairs that leads to the bunker.

The stairs lead to a small room with weapons, food stock, and Spez Dispensers. After lifting up a poster, There is a small hallway leading to another small room. If you step on the middle tile, the room begins closing in. If you press 4 different symbols, a wall opens and you can then go to an even smaller room with surveillance cameras into a computer. After entering a closet and going through decontamination, you can enter a new cave, which is vast and doesn't have any known entrances. All it holds is a freezing/shape shifting machine.
