- Create Mii characters by customizing all aspects of their appearances, and bring them to life by customizing their personalities and voices.
- There are all sorts of activities that you can do with your Mii characters. Find out what they like by watching their reactions to the gifts, foods, and items you give them. Play a variety of mini-games with your islanders or watch them perform songs live on stage. You can also solve their problems to help them level up and unlock new gift items that you can give your Mii characters.
- Create QR codes that save the appearance, personality and voice settings of your Mii characters. If any of your Mii characters have children, you can choose to let them travel, where they'll wander from one person's island to another, all through the StreetPass functionality.
