I agree They should make a Haunted Mansion Playset! It should be the first Horror Genre for a Playset(family friendly of course) and the story should revolve getting rid of all of the evil spirits and the goal should making the mansion spooky and peaceful again releasing all of the trapped good ghostly souls! The Playable characters should be all three hitchhiking ghosts, the Bride, and the Caretaker! the Mission givers should be important characters like Madame Leota, The Organist, The Opera Singer, and the Executioner! In other words, the Haunted Mansion Playset needs to happen! It could bring so much awesome content for the toy box as well!!
Also I don't know if anyone has ever played the old playstation 2 Haunted mansion game that game was fun, but it also used to scare the heck out of me when I was younger!(especially playing it alone and in the dark)! Don't get me started on the screaming banshee lady and the giant spiders that would pop out of nowhere!
