Still trying to figure out how to make the tentacle like things (was thinking foam paint) but then some of the strands are extending off his arms. Then there's also the trouble of making the piece go over my elbow and being able to bend. (Is that where the superglu comes in handy?)
For the spike/tentacle things, I saw some one use spray painted, rolled up news paper with a wire inside to keep it from bending.
Oh, and for bending your elbow, I've seen people make two separate pieces and hook them together.
