There isn't any animal specie that has 9/10 villagers that I like.
If I had to pick, I'd choose penguins. There are 6 that I like and 4 I find decent I guess.
All my dreamies are different species so it's hard. I would say bunnies but my town would be bunnie, carmen, chrissy, dotty, and a million other peppy bunnies.
I like the idea of all squirrels, even though I have none in my town. The squirrels are all cute.
I'd say wolfs if they had more variety in personalities.
