Tomodachi Life is a stage in Super Smash Bros. for Nintendo 3DS / Wii U based off the game of the same name. It only appears in the Nintendo 3DS version of the game.
Design
The stage works similar to the Luigi's Mansion stage, the front walls of the apartments disappear so it's possible to see the area within when a fighter overlaps with the room. The rooms are randomly placed and selected from several types, it's possible to find Miis living in the rooms, the Mii characters are taken from the data in the 3DS system, so it's possible to find friends living in the apartments.
