You can't practically insta-tame them simply by taking your time when tranquilizing them. The more they use their healing ability, the more their food goes down, so when you do knock them out, you can put the kibble right in there and get your taming done right away.
Fun fact:the daeodon is one of the first entodonts aver found?Its also called “the terminator pig” by some who dare see it.These fact are in real life so if you have a test or something you will know where to find this info.(link not included)
So super easy way to tame these guys, Hit them once with any kind of fast moving of flying dino and let them use their healing. After the healing aura goes away Ko them. Instatamed since their food meter is fully empty 😁
