If you go by the Haunted Mansion at night (located in Liberty Square in Disney’s Magic Kingdom), look up in the upper-floor window and you will see happy haunts dancing around the room.

The stretching room really stretches! At Disneyland, it's an optical illusion created by an elevator. But at Disney World, this mysterious and macabre portrait room actually stretches!

At the end of the ride you will find a pet graveyard on your left hand side. In the graveyard, you will also find one for the Disney character, Mr. Toad.

You can see the invisible piano player! Yes, the piano player in the music room is invisible but thanks to Disney magic, you can see his shadow.
