Details
For starters, the cast members here dress slightly different than the butlers and maids positioned at The Haunted Mansion. The most notable feature is the slightly brighter color scheme and the tie being worn has a button resembling Madame Leota's tombstone outside The Haunted Mansion. Multiple paranormal occurrences take place inside the shop: There is a "Spirit Photography" booth in which guests get their picture taken, and have it modified to look like one of the photographs hung in The Haunted Mansion's corridor of doors, giving them a winking eye, coloring their skin blue, and giving them skeletal teeth.
 * A portrait of Madame Leota changes and an ultraviolet light, with eyes glowing in the background.
 * "Bottled Spirits" are seen on higher shelves.
 * A mirror where the apparition of Madame Leota materializes, accompanied by music, then vanishing after a few seconds.
 * Some cast members seem to disregard the paranormal happenings and seem to only take attention to the bottled spirits. Asking about anything else will most likely give the response "I don't know what you're talking about." As if nothing happened.
