Abandoned Tunnels

Right before you slide over the edge, you grab onto the edge of the pipe. It's smooth and slick, but you're able to hold on as your hind paws dangle over the edge. With a burst of adrenaline-fueled strength, you're able to pull yourself back into the pipe. You crawl forward to safety, then slowly stand up. That was close.

You make your way back through the pipe, being much more careful. Eventually, you see a rodent-made structure. It's abandoned, but you see more further down the tunnel. Following the structures, you're able to find your way back to civilization.
