Isn't the section about the captive females escaping big enough to justify splitting it off from the "Rogue Reproductive Behavior" section?
It's interesting to see them using prosthetic limbs, even if it's rare behavior. I wonder if this could inspire some fictionalized account of a Twineshrog missing a limb killing or mutilating other Twineshrogs for their limbs. (I already wrote some dialogue, though who knows when I'll finish it.)
Is it realistic for them to recognize equivalent function to replace their limbs, but not be sophonts? Do they consider their own limbs tools? Do they simply think, "Oh, look, so that's where I left my tail---on a dead shrog's body" and attach it where the tail goes? Do they simply think "that's where a tail goes" as they would regard logs on a nest, or "flat shrog in water look bad, no tail, make it look right, add tail"?
