You run over and pack your backpack with: water and food (in case you get lost.),a sleeping bag (if you get tired in there), a lamp and flashlight (for light, duh). You dart back into the forest cave, you walk in until it gets really dark again, you run around looking for the area you fell at. Later, you find it and fall for longer than before, you grab around for something. After a minute of grabbing at air, you finally grab onto a strangely stable and hard-to-break spike of stone. You sit there dangling for awhile, and remembered the pocket-watch. You swing up and sit on the stone spike and shine the pocketwatch with a napkin that just so happened to be in your pocket. You take the flashlight out of the backpack, turn on the flashlight, and just chuck the watch into the air, and you hit it with that flashlight of yours and it makes a beam of light leading down the hole. You look down and notice theres a wooden chest down there, and not far away. You leap down and wait for the pocket watch, and catch it. You kick open the chest and theres PILES of gold.
