I had 4 argy's, Andrew, the father, Alixian, the mother, Alex, their fist child, and Alexis, their daughter. When I was hunting for metal, with Andrew, a random 150 rex came and ate Andrew, I was very sad when he died. Alixian is still very alive, and a great pet, brave, fearsome, and willing to put up a fight. But.. Just a couple hours earlier, I was on a metal run, with Alixian, and Alex the anjy, and I was JUST around the corner from base, when I seen a sarco eating Alex, and he was on passive and so was Alexis.. It was to late.. They were both killed, and I cried, killed the sarco and cried more. At least Alixian is still alive. But her family weren't so lucky..
