She continued deeper into the cavern, noticing a slight downhill tilt of the floor.   She had to be very careful with her footing, as the floor was coated with some type of moisture.   "Must be all the humidity," she thought to herself, continuing to sweep her flashlight all around the cave walls.   But still she saw no signs of the animal that her sensor repeatedly confirmed was there.  She was a little puzzled by why it couldn't give her a more precise reading...but she noted that several minerals in the asteroid belt above distort her readings.   So it was only logical that there were some of the same down here on the planet.<br/><br/>She was so deep into the cavern now, that she could no longer see then entrance from which she came.   "The Captain would have my head if he knew I was doing this," she muttered.   Finally, she came to an open gallery...the floor of which was covered with a phosphorescent pool of water.  As she scanned the light around the large room, she thought, "Great.   I've come all the way down here for a school of cave fish".
