A Dangerously Tight Tunnel                             -      -     NE 
(-------------------------------------------------)     - <---(M)---> -
 WARNING: You are in a NEUTRAL PLAYER KILLING room.     -      -      -

The underwater tunnel squeezes uncomfortably tight for any creature to
worm through.  Air bubbles can be seen traveling upwards and breaking the
surface in the room just above.  The cavern walls scrape roughly daring to
trap trespassers underwater indefinitely.  The only hope is that following
the parasols of air upward will lead to some refuge from this watery grave.
