Trivia

 * It exists!!

This floor was discovered by finding it's place ID, rather than by completing Floor 4. The place ID is 3488607716. When entering it into a ROBLOX game URL (to get https://www.roblox.com/games/3488607716), the last piece of the URL auto-fills to the name of the place contained within Floor One, which in this case is "Floor 5".
