Ultra Secret Floor is a secret floor that has disco lights and plays Stadium Rave A when the floor is active. Players are rewarded a badge when they find this floor for the first time. During this floor, the floor counter goes up crazy, which can range from 40,000 to 45,000. This is the rarest floor in the entire game!
This floor has a 1 in 20,000 appearance.
Fun Fact: This floor used to play the Despacito 2 song before Roblox's Audio Privacy Update.
