I had wanted to make a Clayface figure for a long time, but couldn't figure out the right base figure to use. I opened up the "mutating" Abomination figure (with Blonksy figure that fits in the back) and it hit me that this would be ideal. Hope it worked. DAS air-drying clay (how appropriate!), two-part epoxy putty and Tamiya "toothpaste" putty, with multiple coats of paint to achieve a muddy colour.
