AHHHH... To all those interested.. there was a mutiny, and 2 of the crabs lost!
Don't know what the heck happened, but 2 of them didn't make it... they were pulled out of their shells and are being eaten by one of the others.
I'm not going to sell the last one, until I can figure out who the jerk of the bunch is, and even then... I'd probably feel bad selling him to anyone else.
