"RIVER OF SLIME"
We Received a call about an unusual glowing substance behind a local sub-division.  It seemed to be growing larger as more ectoplasm gravitated to it.  We set up camp for the night and waited to see what was going on.
We awoke to find ourselves in the middle of a ghost gathering.  Hundreds of spooks have converged around the slime, seemingly protecting it.
PKE levels are off the scale.  The slime river soon started to grow and take shape: into Mr. Stay Puft himself.  We had to fight him off the only way we know how: we crossed the streams...
That night we invited a few friends over for a marshmallow cook out.
