Well when I started my world in my mobile I was just wandering around the lava cave and saw a rex and hide behind a rock and then this motherf@##*r came by jumping off a cliff behind me and start fighting that rex for no reason and after sometime when I built my base I went to collect resources and when I was coming back a sarco coming to eat me but this motherf*#@#r was in front of me then both of them starts killing each other and I ran by side of them
