There have been a couple of rumors circulating lately regarding the Haunted Mansion at WDW. Screamscape reports that they've heard of a possible holiday make-over to tie-in with The Nightmare Before Xmas theme(ala Disneyland). The other is confirmed and pertains to a new animated tombstone that was placed at the entrance of the attraction. Below is a copy of their report, in addition to a link to that page, which includes pictures of the tombstone, for full details of the possible Nightmare re-do.

It seems that creativity at Disney has not been crushed, and a brand new tombstone has been placed in the graveyard at the entrance of the Haunted Mansion. It has been placed as the last tombstone youll see before you enter the mansion and its dedicated to Leota. Even better is that this tombstone is haunted and alive. Weve got a pair of great photos below to show it off, but in general it sit quietly in the graveyard and about once a minute the face on the tombstone lifts slightly, the eyes silently open and it looks around back and forth for a moment and then goes back to sleep. This nice silent effect seems to be creeping out a few guests from the reports I read as one person in a group sees the effect and then by the time they get the attention of the group its over and they look like an idiot. That tombstone looked at me! Yeah right... keep the line moving.
