Me: what would happen if I touched it with a sarco?
Me later watching the cnids suck the life out of my sarco and my stuff fall to the ocean floor and realising that was my only rideable mount who swims.
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.
