You ended up inside a oil refinery located inside a forest. Why would you go explore there? Only you know I guess. SO making your way past the robot spiders that guard the place, you spot a gray armored robot (who has both of his hands and forehead replaced with oil pumps) refining some oil). Then he turns around and notices you Oooh! I haven't had a visitor in a while! Welcome to my humble oil refinery! Do you want some complimentary oil from yours truly? (that's if you can even consume it, of course).
