NPC: A living brain
Long Desc: A bloated, pulsating brain is floating through the air before you.

This seems to be the brain of a humanoid, but you can't be too sure.  It
has a very enlarged cerebral cortex, which probably accounts for its ability
to survive without a host body.  It floats around the room about six feet
off the ground and small bits of disgusting brain fluid drop off hitting the
ground with a small splat.  It seems to have a very high mental capability
and is very much aware of everything around it.
It is a slime approximately 3'5" tall.

This NPC can be found in: Hellbent Mountain.
