Haunted Mansion easter egg:
When you buy and go to Sid's Haunted House in Toy Box mode, talk to Rex, then get the lightning rod. You will now be inside the house. When you obtain all three keys, the door will open and a song will play. This is the same song that the busts from the Disney Haunted Mansion ride sing in the graveyard.
