Today I got attacked by not one but two of these guys first one I was getting my stuff from a obelisk and I was having a drink when I saw this guy run towards me so I dived in the water and survived the second attack happened when my controller ran out of battery so I put it on charge and waited I looked back at the screen to see a allorunning after a turtle and I ran as FAST as I could grabbed my controller and turned it on then I come back to see that I’m not dead turns out my 2 argentavisis killed him cause I saw a allo brain in one of my birds ya argens are the BEST!
