The game takes place on an island inhabited by various Miis, which the player can import from their 3DS, other devices, or QR Codes, or create from scratch using the 3DS' camera or the in-game creation tools. These Miis can be given their own voice, which is spoken in vocal synthesizer software, and a unique personality based on slider inputs given. Miis can then perform various actions, such as eating, trying on different outfits and doing many leisurely activities. As more Miis are introduced, many strange and curious interactions can occur between Miis, such as friendship, romance, rivalry, and even bizarre musical numbers.
