I am currently outlining my next adventure for release and have finished my wandering monsters and over land map. During the creation of the idea for the story (a desert adventure) I decided I wanted to use some creatures I have rarely seen. Gnolls and Nagpas make appearances as well as Lamaras (as anyone can see I am getting use out of that copy of the Creature Catalog I won). One creature I decided to use was one that I have never seen outside a monster manual: The Bulette.
I truly wonder why? I've personally used the Bulette (and a Giant Bulette) a few times in my personal games, but have rarely heard mention of it outside of the monster manual.
So, what unique or under utilized creatures have you, gentle readers, encountered on your journeys through the fantastic?
