This is a new drawing, re-creating my 1980 original from the Advanced Dungeons & Dragons adventure S3: Expedition to the Barrier Peaks (TSR Hobbies, 1980).
I took a bit more creative license on this re-creation than I usually do. I was never happy with the undergrowth I scribbled around the Leechoid on the original drawing, or with my sloppy use of grey tones. Hopefully, everyone will agree that this version is an improvement
