Thanks Digg.. They are like tentacles from a reaper bones monster. The base has this broken hole in the center, originally I was going to have him stand in the hold like he jumped down and crashed through it, but he didn't fit in it. So I put him on the front edge and figured that I would put these things like coming out of the hole behind him.. Not sure what they will say, but I figured it was better than just an empty hole in the middle of the base.
