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. 
Occasionally a room will be destroyed and replaced with a new one.
The Omega form is set on the roof of the house and it's interior cannot be accessed. Interestingly, the Ferris Wheel in the background spins on the Omega form of the stage, but not on the regular stage.
This apartment complex is located in the middle of the island—so convenient! But wait. Why even leave when there's so much fun stuff to do inside? More importantly, what's up with the girl in 301 and the guy in 105? I'm sure someone around here wants to gossip...
With this apartment complex being based in the middle of the island, it's easy to get anywhere quickly. But why leave when there is so much fun stuff to do inside? And just what is going on between the girl in 301 and the guy in 105?! Maybe we'll find out the next time someone throws a roof party.
The stage is based off of the Tomodachi series, specifically Tomodachi Life. It takes place inside various rooms in Mii Apartments, where players' Miis reside.
- Tomodachi Life
- Mii Plaza
- If this stage is played on multiplayer, everyone will have different Miis show up.
