I tried taming one of these a while ago. I managed to knock it out and started the long process, using tons of citronal and narcotics. I spent most of it hanging out next to it with my raptor, waiting until the taming would finish. However, right as the taming level was in it’s final few percentages, a group of raptors attacked us. I was terrified they would kill the therzino and undo all my work. But then, it suddenly stood up, completely tamed, and tickled all the raptors to death. Very intense experience.
