This mod is now mostly done and functioning! Works almost exactly the same way as it's sibling mod TameBeasties, but with a few changes here and there.
1. Find unconscious Beastie
2. Put the Beastie in your cage by clicking either the Lock or Unlock option
3. Talk to the Beastie and "feed" it the right food to gain it's trust
4. Pick up your new friend from the cage and place it down
