I love smugs, lazy and normals. I have always had multiples of these, up to 4 per personality sometimes, as long as their birthdays were months apart I found them to be slightly different with their dialogue at times. When I had punchy and beau at the same time it was like having the same villager twice. Their birthdays are both April and they were best friends, every time I saw beau it was just like having 2 punchy's. Same with chief and fang. I think their birthdays are a day apart or something. I would love to get chief back as a friend for fang but they're too much alike
