Ricky at Inside the Magic has a video of Disney's Haunted Halloween Parade at Tokyo Disneyland.
All of the floats have Haunted Mansion themes – even obscure stuff like the Rolly Crump designed overstuffed easy chair with the face worked into the design. Another float has the Ballroom's Organ as the major design element. The Knight from just outside the endless hallway is represented by 4 cast members. The bride is a chipmunk character. Another float has a giant representation of the skeletal arm with a trowel bricking himself into his own tomb.
A phalanx of Haunted Mansion maids leads the parade. Ghosts from the Mickey Mouse cartoon "Lonesome Ghosts" pepper the entire parade.
The song that accompanies the parade is called "One More Ghost" in reference to the need to find that 1000th ghost that the Mansion needs.
The show stop at the end of the parade features the Japanese Ghost Host voice with various riffs off of the Grim Grinning Ghosts theme.
