The best way of taming one of these is placing a 2-4 beds near the andrewsuchus ( depending on how many honey you need to tame it ) , place a storage box , put all of your items inside the storage box except for one honey , go to it , do the first ride and just let it kill you , respawn in the beds , grab another honey and you can just re do it without any trouble , the taming won’t reset and he won’t agro to you , keep on doing it until its tamed :) , it is the best way to do it early game , i tamed a high level first try with 5 rides only , it should’ve been 4 but i missed up the controls a bit and had 2% left at the end
