After reading through the (terrible) “Big bionics?” thread, I came to the conclusion that actually having some mutations to counteract the steady stream of grotesqueness modifiers you get with mutations would be a good idea, so I went ahead and added 4 new traits/mutations:
Pretty, Beautiful, Very Beautiful, and Glorious.
Their effects are pretty much the opposite of Ugly, Deformed, et. al.
So I guess something good came out of that mess after all.
I was trying to figure out how to mess with the mutations code, but got derailed at the point where they turned out to just all be flags. Might take a shot at giving 4/8 Tentacles the ability to Grab on a crit, rather than the constant Slap–I think that only affects the melee code.
