My favourite is Hamphrey the Hamster. He's adorable!
I think his cranky personality suits him well.
My second is probably Chadder the mouse or Bam the deer
Walker <3 I wanted him in Wild World, started up City Folk and he was there, and I'm so happy to have him in New Leaf. I love the Lazy personality and he's just the cutest dog.
And in my cycling town, Zucker (who I also have in my main town <3 ) because he never leaves lol I've cycled through tens of villagers and Zucker is just stuck there.
In my town right now, I'd have to say that Bluebear is my favorite, followed closely by Blanche and Ken.
Back before I restarted my town though, I was basically in love with Walt the Kangaroo. That grumpy marsupial called me "Old Sport" and made me weak in the knees.
Beau will always be my favorite villager ^.^ Kiki used to be my favorite, but I got Beau as a starting villager and now I'm just absolutely in love with him. He's just such a sweetie. I got Flurry as an impulse buy which I don't regret even a little, 'cause now she's my second favorite. So conclusion: Beau and Flurry right now are my favorite villagers!
At the moment Tangy is my favorite. I'm not planning on keeping any of them at the moment though.
The reason I think Tangy is just great is he never has anything negative to say and he seems a bit unique compared to my other villagers dialogue-wise. I'm tired of getting asked for time capsule burials and fish/fruit trades. He's really nice-- plus he's just adorable with the little leaf on his head.
I'm getting Bianca here in a bit, really looking forward to having her around. She'll be the first villager dreamie I've gotten.
