So Dilos are pretty common so you could easily find one. Carry a club with you and kill a few dodos so you can get meat. Then find a dilo (like I said before it’s easy to find one), knock it out with the club, and feed it meat (I think you only need 2-3). And you got a tamed dilo!
1.kill some dilos, dodos or compy so that you can collect meat.
2.Craft a slingshot, wooden club or you can beat it with fist (If your trying to knock it with fists choose a low level one; if with slingshot collect a amount of stones first also remember wooden club breaks fast so craft and keep atleast 3 more wooden club for backup)
3.Find a dilo
4.after it's unconscious open its inventory by going near to it and tap and hold. After you need to put some meat which we collected at first
5. Wait.....if your dilo eats all the meat but still not tamed put some more meat to its inventory and wait......
