Once me and my friends in a private server were on the south eastern island(you know the passive one with metal rocks) and everything was going well, until we went to the mainland (we didnt know these existed at the time) and all of a sudden this huge white thing came up and destroyed our boat we were all screaming, it was an alpha, we trapped ourselves on that island for so long until I gave up and killed it with admin commands, but not before trying to kill it, it ran, it wasnt even bloody but it ran.
Once me and my friends were heading to our town on herbivore island, and then this thing comes. It's like out of Moby Dick. One of my friends shouted "ABANDON SHIP!" And jumped into the ocean, swimming to shore. Me and my two other friends stayed on the ship, with our rifles ready. Then my friend who abandoned us tried to help us by shooting the beast with a bazooka. He did manage to kill it, but he killed us and the raft too. We have since put handcuffs on him, and put him in our prison in the cave in carnivore island.
