The New Scooby-Doo Movies
After Phyllis Diller is called by Madame Zokar to attend a séance regarding one of Diller's late husbands, although the séance turns out to be nothing but a trick to get Diller to reveal where her husband left his jewels after he passed away. The Mansion itself functions as an atrium for magic shows and séances. It features numerous passageways and corridors as well ghosts. Apparently the Magic Mansion is bigger than it seems, since Alberto states that there is a Dreary Dungeon and many more unspecified areas of the house.
