Here’s how to tame a carbonemys, first build a U shaped house. Make sure it has two doors at the ends and one door in the middle. Put a foundation in the outside of the inside of the U, leave the inside empty. Once you hit a carbonemys lead them into the inside, then place a wall so it doesn’t try to run away. Then you basically just knock it out.

This idea was dumb. BUT TRY IT OUT ANYWAY. Hope this helps low level noobs.
