Are there any nods to the Haunted Mansion?
From the video, there seems to be a few, but I am not sure if they are true tributes:
I could swear the organ in the music room is playing a fast version of Grimm Grinning Ghosts
Picture turning into Medusa (that one is a little more obvious)
One thing that is consistent with all the Haunted Mansions is the ghost Phennous who is the skeletal hitchhiking ghost. Does he appear?
