These creatures are great! The only thing is there slow. To tame them all you need is

4 stone foundations

16 stone doorways

And 4 ramps

Now you build a 2x2 then make it 2 stories tall with the doorways. Put the ramps on the side you want it to go on. Then shoot it with your tranqs so it chases you. Run into the trap and exit through the doorways. Shoot it with tranqs and you can either starve it or feed it right away. I personally like starving it. Feed it superior kibble, bee honey, or prime meat work the best but if u don’t have any of those just use normal meat. And now u have yourself a great big friendly sloth
