A main feature in Animal Crossing: New Horizons is the campsite, where random villagers visit approximately once a week. Players have the option to invite these villagers to move to their islands, but there's a catch: Unlike when players invite campers using amiibo, random campers will ask to replace random villagers. Players ostensibly have no control over the choice, unless they use this trick to swap villagers.
