A lot of people here are saying that the 10th villager to move in is from wifi/streetpass but I had a villager move in without either of those. Roscoe moved into my 10th slot before I had visited anyone's town (besides my bf's) and before I even had enabled streetpass in the game. He originated in my town. He has no history except for the few weeks he had wit me. So does anyone really know if villagers truly just can randomly appear or not/
