So..., I just tamed a lvl 28 parasaur, he was very pretty too, green and light greenish white. My base was just a lake/river away. I figured I would cross with my parasaur following me. And I swam, I was still a noob, and I wasn't very fast at swimming. So halfway into crossing, a group of megapiranhas attacked MY PARASAUR and I thought he would attack them, but I watched in horror as his health kept decreasing and decreasing until he died. And the worst part is, that he died just before reaching the shore. Rip Mr.Parasaur
