Stinkweed was designed by Gabriel Barragan (Lazzy Lizard), who has been collecting toys for as long as he can remember in addition to customizing and designing toys for nearly twenty years. He said that he drew inspiration for Stinkweed from an Andy Panda cartoon in which a weed character was terrorizing his flower girlfriend. Stinkweed is a much more detailed update.
I think this might be my favorite transition from concept to sculpt of the first six Run-A-Mucks. Bask in the glory of this MS Paint mockup of the plant formerly known as "Potman." I love it.
Then the design was updated by Christopher Howard Wolf of www.slimebeast.com . And here it gets a little interesting. On the right is the original detailed version of the art for Stinkweed, however, on the left is the only reference art I had for my sculpt. So making a few changes for practical and molding purposes, the Stinkweed sculpt is of a more stalky, tough-looking guy. Only after I was done with the sculpt did I see the original art for the first time and contemplated changing the sculpture into the more slender, taller-looking version, but Gabriel and I were both happy with it, so no changes were made. It's pretty cool how having the reference art out of aspect actually made him look like more of a mean bruiser…wouldn't want to meet him in a dark alley.
Stinkweed is of pretty average height, though he has more mass to his stalky, broad form than many mini figures. Compare him here, from left to right, to a Battle Beast figure, a Mystical Warriors of the Ring toy, an OMFG mini figure, and as always, a classic M.U.S.C.L.E. toy.
