Ever use Sleestaks in your campaign?

Neither had I!

I went even further back in B/X box set days and made up stats for the "snake that speaks" from Howard's King Kull stories that took place in Valusia. None of my players had read the material, though, sadly

I think I also may have portrayed troglodytes as somewhat sleestak-like around the same time period, but forgot to use the crystals, just the hissy breathing. Would have been circa 1982-83.
