Only two ever spawn in world, if you kill either of the pair they will never respawn or spawn more. So be careful and do your best to grab it while you have the chance. One male and one female, lvl shouldn’t really matter since in essence they are just special skin horses. They tame the same way too, ride it and feed it. No idea where they spawn but they spawn everywhere. Raid herbivore island and wait for the spawn. It took about 3irl days for this to work and it messed up when the power went out for a split second.
