I had Bubbles and Rocket one time, but they left after cycling them out, which took me an hour or so (which is quick, since sometimes, villagers won't leave for months or even years.) They must understand me.
So let's settle with Hippos and Gorillas for now.
Favorite: wolves! (But I like ducks, deer and cubs too)
Least favorite: I guess mice. I'm not a big fan of the in-game design and there is no mouse that I think I might want to have in my town. About every other species has at least one that I wouldn't mind.
Least Favorite: To tell you the truth, I don't have one.
Although I don't like this one villager, it really doesn't mean that I hate that species in-general.
All of them have this uniqueness to them, which I can get down with...even if their personalities are basically copy-pasted.
My favourite is the wolves. Their designs are really cool
and my least favourite are probably kangaroos and chickens. Wish they made other species, like bats or ferrets
Favorite: Deer! Theyve been my favorite irl animal ever since I moved a few years back. My old city had deer everywhere and they would just go up to your doorsteps and it was really nice and i miss it so much! Plus Bam is one of my favorite all time villagers and i think all the deer have really nice designs!
Least I really cant stand the bulls, cows, or hippos. Everything else i dont really mind but ugh I cant stand those
I feel like I still haven't had most of them because I got so used to my original villagers, I never let them leave...but so far from who I've had:
Favourite - Deer (I love Erik, so cute!!)
Least Favourite - Mice...I have 3 in my town right now, BORING
I really would like an octopus villager...and a dog.
