Becoming best friends with another player outside of your Animal Crossing: New Horizons game is a great way for the two of you to work together on a singular island. When you visit an island in multiplayer, or have a friend come over to check yours out, you can make them a best friend.
To make someone a best friend you first need to open your NookPhone and add them to your list of best friends in the smartphone’s application. You can see any player you’ve interacted with, and from that list, you can pick which ones you want to make a best friend. You don’t have to type in their name, add their Nintendo friend code, or have any additional information. It makes the game’s multiplayer and co-op mode a seamless experience.
When you make another your best friend in Animal Crossing they can freely modify and edit parts of your island. By default, whenever you invite another person to visit your island, they don’t have this ability. For anyone you want to have over, but not stay for too long, you likely don’t want to grant them access to changing how you have things. They could do something by mistake, or worse. When you make someone your best friend, you need to make sure you choose wisely and think about that decision.
After you know how to label another player a best friend, things should become extensively easier to complete in the game while you roam around an island together. Those who are not your best friend have limited access to what they can do while visiting your island.
