The Debutante Ball Car is the main setting for the episode "The Debutante Ball Car" in Book Three. A fancy ballroom where Octopus People dance.
Overview[]
Inside this car is a massive golden ballroom, complete with a grand staircase and a talking chandelier. The exit door is only available to passengers who make their "debut," receiving formally training from the Chandelier via learning a special ballroom dance and dressing in proper ballroom outfits. The denizens of the car are a group of Octopus People, dressed for the occasion and speaking in upper class accents.
According to Simon, the building housing the ballroom exists within a black void, meaning it is impossible to enter or exit the car unless through the doors.
