Give Roach Mutantrace a new gimmick ability

[Bartimeus]

What if molting would consume a chunk of hunger and thirst, heal you for some amount, but also leave you even more vulnerable to damage for a time while your carapace hardens? You could molt once in a long while to heal minor damage, regrow a limb or two (or regrow a shittier version of it, which is funnier) or to leave a decoy of yourself behind, albeit a very obvious and fragile one. It'd remove things like paint, gnesis colorings or similar. Molting would also likely take a fair bit of time. Perhaps fully regrowing a limb would require several moltings, so you can get rid of it's inferior version.

About the headless roach suggestion, what if headless roaches just randomly ran around sometimes for several minutes before finally dropping dead? One last hurrah before finally keeling over or before a doctor can reattach your head.

Perhaps roaches could be completely silent when they run while lying down, as a skittering critter, though that isnt as fun.
