If I were forced to choose just one, I would say Fauna. I also think Zell, Rosie, Felicity, Molly, Blanche, Bill, Poppy, Bunnie, Diana, Flora, Maple, Tia, Blaire, Sylvana, and Ellie are right up there. These are not necessarily my favorite villagers (though a few are), but the ones that I find the most aesthetically pleasing. One of my all time favorite villagers is Frobert. But he is not on this list even though I think he is adorable.
