Name him Salami, as he has a very strong appearance but a soft heart. Aim for the head, not the shell, he likes his shell. He likes giving free rides if you manage to get on his shell. Tell him his homie Merk sent ya. ~Tundra
So i was taming one for someone else, i did not know i had my compy. I also did not know it was mate boosted, the turtle. When the other turtle attacked, my shoulder compy went in. It died RIP Lizard PRAYFORLIZARD
To get higher level "war turtles" tame 2 level 150 turtles and then breed them. Then go tame another turtle of the opposite sex to mate with the hatched turtle and do it all over again. Once you've done that you can breed the two offspring over and over to get very high level turtles. It is super easy to hatch and raise "super turtles"....lol. Good luck and enjoy
You can find it at a water area (I found it at the edge of the map). To knock him out, for starters, use a slingshot. When he is down bring your narcotics and berries. If he is unconscious and you fear he will wake up, punch him a few times to keep him like that. Congrats, you now have tamed a Carbonemys. Hope this helped.
Side note: if you want to be safe, through a bola and hit him with a bat to knock him out.
