If your on mobile and can’t find one of these guys start the tame equus pursuit and walk or fly around the island and eventually a arrow will show up on the top left of your screen. If you follow that then you will find an equus or two. Upvoote if you found this helpful.
Run run run, crouch when close still approaching at an angle, when close enough,(stack of carrots in zero slot) click three “e” three times; one to feed, one to mount, one to start THE RIDE! Each time you get the feed prompt, hit “e” and pray it gets stuck in a corner and doesn’t run off a cliff, or into carnivores. Ignore everything but the prompt, hitting “e” without hesitation. (You cannot control the run at all). That’s it.
