Wii Fit Studio

Wii Fit Studio is a stage from the Super Smash Bros. series introduced in the Wii U iteration as a representation for the Wii Fit series. It is a plain studio room with Balance Boards that appear occasionally as platforms. The living Wii Balance Board from the games also makes a cameo.

Stage Features
The stage is rather basic being a studio room with walk-off boundaries. The stage typically has a mirror in the background reflecting the battle. There is also an exercise bike and treadmill. Occasionally, the background turns white with a (male or female) Wii Fit Trainer's silhouette appearing, directing the players on how to perform a certain exercise, but does nothing otherwise.

Ever so often, Wii Balance Boards descend from the top of the stage into arrangements. They stay stationary until they leave but there are 125 possible arrangements for the boards to be in. When the boards ascend, they do not star KO players still standing on them.

In the 8-player form, the mirror does not appear and the background is plain.

Music
The bolded tracks need to be unlocked while the italicized tracks are returning music from a past game.
