I was swimming with my sarco when these morons came and attacked me. I lost all my stuff, and my sarco. To get back at them, I lured them onto the surface and watched them die. Sweet justice.
Never go near it with your Dino, it will kill you, your Dino, your friends, your family, the guy down the street, some guy over in Africa, all while they won't do a thing to attack it.
