You take the door out of your backpack and place it on the wall, it seems like it still works.
You enter the door in hope of something useful. The room is filled with bananas, trees and other jungle-ish stuff. You find a little monkey that looks hungry, but he doesn't seem to like bananas. You feed the monkey with some food from your backpack and it decides to be your companion. (Probably just because he wants more food)
You leave the door and put it in your backpack, now you use the lighter to set the bullet on fire and use the gun to shoot the bullet at the barrel. The barrel makes a fart sound and the hole somehow gets bigger, you enter the hole and are now on a upen field. You can see a forest, a lake and a city.
What to do?
