The pipe is wet and slimy, but you crawl on into the dank darkness, slithering and sliding as you go.  Suddenly your hand hits something hard and square which feels as if it is made of wood.  It rattles as you shake it, and you decide you must be holding a box.<br/><br/><em>Your choices are to crawl back out of the pipe and examine your find, or to press on further down the pipe, taking the box with you to examine later.</em>
