Tame a kaprosuchos and swim to one of these bad boys and do it's alternate attack it will grab it in it's mouth. walk onto the shore where its safe and have another person feed it while in the gators mouth (if you unmount it drops it) it wont attack or die because it's technically not on the shore.
Guys it says passive tame because you don't need to knock it out🤦♂️ anyways, whoever said they only eat angler gel after tamed is a liar. They eat meat too. This deathly pancake is a good tame. Here's how to tame it: 1. Find a manta (if you're on the island theres some near the little lake thing where you spawn)
They have terrible turning circle, approach one from above and feed it. Then let it swim circles around you. The occasional time it gets close you can predict its attacks, it “bucks” just before the attack, which is the tail swinging underneath. Quick swim up or back avoids it. Be prepared to get dizzy, long time between feeding
