Roscoe is easily my first choice for favorite horse villager; at one point he was the only horse that I liked, but over time from reading threads and talking to others about the villagers, I’ve grown to like a few more. I always have loved Roscoe because of how unique his appearance is and I love his design. I like his red eyes and when he gets mad, he really looks mad and his facial expressions are really good

I only voted for Roscoe but there are other horse villagers I like. Most recently is Buck, thanks to

. I never actually disliked him; I was just neutral on his design. But, I think his design is growing on me and he seems pretty cool!
I kinda like Cleo too; need to see her more to form a stronger opinion I think.
I had Reneigh and she was okay when I had her; I don’t think I talked to her enough to have a strong enough impression at the time. Her design is pretty good! I’m not much of a fan of sisterly villagers so at the time, I didn’t have a good enough impression. But I think, now I can safely say I like her.
