Shambling mound is a classic D&D monster, in the Monster Manual 1st ed is described as:
” a heap of rotting vegetation, the shambler is actually an intelligent form of vegetable life. It is generally from 6’ to 9’ in height, with a girth of about 6’ at its base and 2’ at its summit. “
This is an old school miniature, it belongs to the Ral Partha range of models licensed for Advanced Dungeons & Dragons. The production period lasted from 1987 until 1996 when Wizards of the Coast started making their own line of D&D models. The internet says with the end of the license Ral Partha was forced to destroy all the master molds of the range.
So, in theory those models are gone forever, or at least this is what ebay tries to make us believe.

The Shambling Mound is part of the Ral Partha AD&D Monsters range, #11-493 to be more precise, it was sculpted by Dave Summers, and I hope some day he will read this post because I LOVE THIS MODEL!!!! I find it such an amazing sculpt!! so full of personality!
I had such a great fun painting it!! Thank you Mr. Summers!!!

Also I´m amazed with the challenge of molding it, I have very little experience molding but enough to realize somebody did a great work molding this sculpt in a single piece with such a level of deep details modeled.

Here you have a couple of images of how the original blister and unpainted miniature look (shameless stolen from www.miniatures-workshop.com ) check out their Ral Partha catalog to see other old school beauties
