This was me 4 days ago. You guys told me to use the raft and i did. I collected the most from my old base, build a raft and started sailing with my trike and moschops. Yeah that went terrible😭. I tried to keep my distance from the swamps but some random sarco still found me.    I tried again but this time it worked i was on the other side of the island. While sailing i spotted a 135 level pteranodon. I tamed it and currently it's level 218. I set up my base on a cliff behind the hidden lake. Soon i saw a yellow drop in carno island. I went there and for some reason when i got of my flyer, it just randomly started flying to the main island. I checked my map after and his icon was just stuck in the middle of the ocean. I was stranded. Thankfully i had resources with me, i crafted bolas and spotted a 135 level raptor. Taming him almost made me lose my mind but thankfully i was able to bait the predators away and was able to get my raptor 99% taming effectiveness. After some more progression, i decided it was time to get an argy. I went back to carno island, and found a level 140 argy. I build a trap that i saw on yt and it worked perfectly. I knocked it out fed it and again used myself as bait for the predators. Just running around on the rocks made the predators lose interest in me, soon the argy tamed and i hopped on my pteranodon and flew back to main island. I got a gem of an argy, dude is insane.
