Golgath asked to see these, and I like them so I figured other people would want to see them too. I don't think the appearance numbers are working quite right, and there might be some other problems. I made these a while ago (like 38b I think) but they should still work. At any rate, take a look, tell me what you think, and feel free to add parts to your own worlds. And yes,
this basically gave me the idea.
First, they all use these body parts (tagged for size)-

Crabman, 'cause where would a crab mod be without them. Built out of snakeman code, and they should show up on coasts and in cave lakes/rivers. They're actually bigger than dwarves, so watch out.

Big enough to wrestle giants, and armed and armored enough to win, these crustacian colossii are the bane of all coastal settlements. Not thoroughly tested - I wanted them to just be rare wildlife, but they showed up way too often (nearly always). I made them into megabeasts, but I don't know if that means they'll show up far inland and in caves, or if the biome tags will prevent that.
EDIT: Modified them all with suggestions, and added Dwarmin's nasty GCCrabs.
EDIT2: Added crabmen, and put STOUT tags on all the smaller crabs, because otherwise it's just be silly.
