"We have 999 happy haunts here, but there's room for a thousand. Any volunteers?"The Happy Haunts are the ghosts haunting the Haunted Mansion.
—The Ghost Host to guests
The ethereal inhabitants of the Haunted Mansion are often referred to by the Ghost Host as the Happy Haunts. Walt Disney began collecting these ghosts to live in his Haunted Mansion and successfully nabbed 999 of them in time for the opening of the original ride on August 9, 1969, despite having died three years before (although some of them already haunted Gracey Manor before it was turned into a retirement home, most notably the Ghost Host, Madame Leota and the Black Widow Bride). Happy Haunts vary in appearance, from translucent people-like apparitions, to slightly rotten corpses. Nonetheless, they all enjoy their life in the Haunted Mansion, and they enjoy the company of the living, without frightening them too much.
