That's a good looking prop.
The easiest way and something I've done is to take a 5 gal bucket and fill with quick set cement. After mixing in some water I'll place a cut down piece of electrical conduit (or you can use PVC) and insert into the bucket. I'll have the pipe sticking up by a foot for instance and then I can slide another piece over the one in the bucket (e.g. 1" might be used in the body of the prop but it's 3/4" in the cement bucket).
I've used this to anchor something like a demon prop that had a robe like costume. The 5 gal buckets won't work for your 2 legged prop so you might need to do a combination of quart sized buckets or paint cans or possibly large boots filled with the cement (kind of adds meaning to sleeping with the fishes).
