You don’t need Ghillie for it. Just crouch once you’re close enough, slowly approach it from behind, and feed it kibble or carrots. As long as you stay crouched, it won’t run even if it turns toward you.

A Tek suit makes things a lot easier because after each feed it burrows underground and moves a fair distance away. With a Tek suit, you can catch up to it much faster.

If it says “doesn’t want to be fed right now” or “not hungry,” sometimes it bugs out and won’t update properly. What usually fixes it is leaving render distance and coming back. Once you return, spam the feed button and it should take the food.

Also bring a shield. If you get trapped in its pit, pull your shield up and keep it raised while spamming the punch button to escape. The shield blocks the damage while you break out safely. Once you’re free, run away until it stops glowing yellow and then go back.
