Unfortunately, none! Elvis was the last original villager I had but it's been a long time since he moved out. I think I kept him for a year before moving on to get all my dreamies. My first letter to my town's cranky, Rasher, mentioned that he was replacing Elvis, the last of my original villagers. Both Bob and Merengue moved in naturally to make up my first 10 villager set though and I still have them in my town!
With my last town I had Gengi Monique, Lucha and Walker. I planed to move them all out as fast as I could but they really grew on me. Eventually I let them move out but I kept flower memorials for them lmao. I decided to keep Lucha, as he ended up being my favourite, but I accidentally TT'd him out.
