I have a few permanent villagers. Sydney and Antonio because they are my new favorites and I love them so much (not to mention that they are OG) and possibly Coco but I have her amiibo card so I can invite her as I please. Audie is also a favorite, and Raymond was just a pain to find and the only other smugs I like a lot are Toby and Eugene. And there’s of course Zucker. He is blooping (bad joke lol) never leaving my island.
In terms of villagers to move out, I’d be fine moving out Lily or Coco even though I love them so much because I have their amiibos. I invited Phoebe to my island to see what she is like, and if it turns out I’m not fond of her (I don’t know what to do with her house now because it looked a lot better when Static lived there) I’d be fine moving her out.
At some point, I want to invite Amelia, Anicotti, and Boyd all to my island. I haven’t ever really seen them on anyone else’s islands and I love their design!
