NPC: A pig nosed bat
Long Desc: A pig nosed bat flies nearly out of sight above you.

Eying you carefully, this bat is known to you as being poisonous.  Its
venomous fangs have a sharp twang of toxin to them.  You recall seeing
someone bitten before, and it wasn't all too pleasant an experience to
witness.  It begins to stir more as you approach it.
She is a bat approximately 1'6" tall.

This NPC can be found in: Sigil Underground.
