Today I was just chilling looking for something that could help me beat the manticore and I literally saw a white thyla and I was so lucky that it was trapped in one of the rib cage structures then I got like my club and I smacked it in the face then it went down I gave it raw meat but then I noticed it it cooked meat then I gave it cooked meat and it was almost waking up so I force feed it nicroberries then I finally tamed it you can also try using doorways stone doorways (I think) or you could use normal structures that the game generates
