Beau! I lost him in my first town after I reset, and within the first week of making my new town he came by chance! He is my number one dreamy, and I'm glad I have him.
TBH, it's Stitches. he's always coming over, always giving me stuff, we write each other, and when he talks, I just get him. I think I'd be a lazy villager myself, always napping and hungry, lol.
I love most of them! O'Hare and Camofrog I really enjoy being round, as Camofrog can be a good laugh! Although Merry and Chevre have been in my town since I started the game, so I suppose I love them too!
In Wild World, I loved all my villagers, but it was Rocco and Melba that stood out to me.
In Stardust, Wolfgang and Anchovy were my babies. I got Rocco back from someone's town, as well as some of my other WW villagers, but I never once saw my precious Melba.
In my current town, I can't really name a favorite, though Truffles and Pancetti are nice to me. I had Erik for awhile, but because I'm fast-forwarding through my town to catch up to the current date and time, I lost him and a few others. Colton, if I can forgive him for destroying a good portion of my perfect apples, would make a nice friend, too. Drake was adorable until he left, too.
I still want Melba, I still miss Melba, and I still love Melba. So she's my favorite.
