The "Hitchhiking Ghosts" are a popular attraction at the Haunted Mansion ride in Disney theme parks. These three ghostly characters—Ezra, Gus, and Phineas—are known for their playful and mischievous nature. They appear in the ride's final scene, where they invite guests to join them on their ghostly adventures. The concept of the Hitchhiking Ghosts is based on the idea that they can follow guests home, creating a fun and spooky experience. The ride uses advanced technology, including animatronics and projection effects, to bring these characters to life, making them a memorable part of the Haunted Mansion experience.
