You need to lure a fish swarm (found deep in the ocean) to a megachelon it will then swarm the megachelon and begin taming. *Note that you don’t passive tame this creature with meat it is false, you can however knock it out but it takes a long time for it’s torpor to rise, if the megachelon takes damage it’s taming resets*
DON'T BOTHER DEFENDING THE TURTLE FOR 30 MINUTES!!!! Lure the swarm to it and then just leave render... If no one is near the turtle while the swarm tames it nothing will bother it and it'll tame out on it's own... EzPz
Ps: If ANYONE is in render it won't work, so wait until pop is real low to use said strat.
