hes sculpted form a huge pice of SOFT FOAM, much like what piggy and the other muppet show pigs were .its denser, stretchier,and last longer than other types of foam, its very soft , easy to carve, dont no were to ordeer it (i have a feeling it is a custom order,)
but it is really nice stuff, it can be dyed, and painted with flock glue(go to puppet design , patricks website, ) he carved a little alien puppet out of the same stuff recently
