This just in!
We finally have an airdate for Muppets Haunted Mansion, it'll have its scremiere on October 8, 2021, on Disney Plus.
Additionally, a portion of the Muppet and cameo cast has also been listed.

as The Ghost Host.

as Madame Leota Tombs.

as the Hatbox Ghost.

as Mr. Suel, one of the duelers; and Pops as Mr. West, his erstwhile adversary.
Chip as Pickwick, the ghost seen hanging from the chandelier in the ballroom.
Beautiful Day Monster, Howard Tubman, and Beverly Plume as Ballroom Dancer Ghosts (which is weird because that's a trio when the HM has six different pairs of ballroom dancer ghosts).

as Alexander Nitrokoff, the guy in his shorts on top of the powder keg about to explode;

as Sally Slater, the tightrope walker; and Link Hogthrob, Dr. Julius Strangepork, and Miss Poogy as the Quicksand Men, all from the Stretching Room Portraits. Again, weird that Poogy's one of the "Quicksand Men", shrugs. Constance Hatchaway/Abigail Patecleaver is notably absent to complete the portraits.
There'll be human cast cameos as other ghostly characters included in this 48-minute special. Stay tuned for other hexciting developments.
