Never park your dinos on the beach for any amount of time. Everything I’ve ever cared about in this game has been killed by a Theri. I’m still early but verging on mid-game, and had tamed a small pack of dinos I was proud of: a Sarco, my Ptera, 2nd generation Parasaur (parents killed), 2 Carnos, 2 Raptors and their juvenile, a Dilo, my Diplodocus sweetheart, my newly tamed Anky and my monkey. All murdered in a matter of seconds. If I hadn’t put stone foundations on my raft, that would have been gone too. The only survivors (miraculously) were my Moschops that I pumped health into. I’m still in shock. Damn you, murderous tickle chickens!!! WE HATES IT!
