Crabs pinch. I got pinched before by a crab. Crabs just try to pinch you when you are holding them by the back. You can hold them by the leg and then they can't pinch you. You can try to destroy them in self defense. You can step on them, really. You can put soap on them to try to destroy them. You put a little soap in their pinchers and then it gets a lot of legs and pinchers off.
