Taming it is quite simple, it’s just like the pegstomax. Once it spots you it’ll come after the raw fish meat in your inventory- it’ll kill you a couple times so you just have to keep coming back for about an hour. I suggest building a base nearby! And once you’re finished taming it you can unlock some sick oil areas, and get a infinite ammount of fish. Keep in mind that there is only one per map, so I suggest doing this sequence in singleplayer, riding an icthy is helpful while taming this bad boy.
