When you are on it and it bucks, tap the carrots down at the corner. You should have them ready and it doesn’t take that long with carrots, but it will with somethings. And the spawn all over the map. Like if this helped pls!
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.
