The Ghostly Trio are the Casper's adopted uncles and minor villains of "Casper's Haunted Christmas". Their names are Stinkie, Stretch and Fatso. They were excellent scarers until Kiboshi's assistant Snivel, took their haunting licenses by breaking the law. They try to teach Casper to be the scary ghost, but fails because Casper is too friendly, much to their dismays. Like Snivel, they are afraid of Kibosh. If they do scare with their haunting licenses, Kiboshi will banish them to "The Dark", a ghostly purgatory.
