Maybe Gaston. His house creeped me out but then when I got to know him, I dubbed him my "funny bunny" and now he is never allowed to leave my town.
I used to dislike Ribbot too, but after he changed his mind about moving three times, he grew on me. I eventually did let him leave though. I'm happy I get to see him on Main Street though. Sometimes I miss him.
Merengue as well for me, because I was always used to having the little, cutesy animals like bunnies and cats in previous AC games. When I first started New Leaf, my starting villagers were Ribbot, Camofrog, Rosie and Merengue, so she was like the odd one out for being so tall and huge.
Aw, yes, I really liked Cyrano and I let him move just to get some new faces, but I really miss him. I sometimes forget he moved away and get sad about it.
I really like Pietro, didn't think I would, but he grew on me. I think his catchphrase makes him seem extra adorable.
O'Hare. I don't like the smug personality at all, definitely my least favorite, but he was so cute and the personality gets better the closer you get to them.
Mathilda, Marshal and to a lesser extent Deirdre for me.
Mathilda was one my my original 5 in my old town. Didn't like her much at all, and found I was really saddened when she went to leave. ~ we used to dance in Club LOL together.
Marshal I didn't think was that cute, and then he camped in my town when I happened to have a space and just couldn't not have him.
Deirdre I have in my town now, she was never a dreamie until I realised I only needed 2 more deer to have the lot between my towns and I don't really like uchi's much but since she's moved in I now really like her.
Anabelle. I thought I didn't like anteater villagers, but I saw her in a dream town and thought she was pretty cool. Now I've had her in my town for a long time and she's a favorite
