You are deep within an overgrown area of the rainforest, beneath towering
trees which loom ominously overhead and block out almost all of the
sunlight.  The rainforest is home to many rare plants and animals on the
verge of extinction.  You get an excited chill down your spine from the
calls of the wild animals, as you carefully move your way through the
jungle.
