Lonesome Ghosts

The Lonesome Ghosts are four green phantoms who appear in the 1937 short Lonesome Ghosts. They are ironically afraid of ghosts themselves.

Lonesome Ghosts
One night during the winter, the ghosts were alone in their mansion complaining about the fact that there's absolutely no one left to scare. Soon enough one ghost finds an aid in the paper about Ghost Exterminators. They call with the shortest ghost disguising his voice claiming they're being haunted. The exterminators, Mickey, Donald and Goofy, head to the mansion. They are then locked in and tricked, scared, and teased by the ghosts. Eventually, the trio accidentally crash into barrels of dough, giving them the appearance of ghosts, scaring away the Lonesome Ghosts.

Epic Mickey
Since the Mad Doctor arrived in Lonesome Manor and the pipe organ went out of order, the Lonesome Ghosts settled into Bog Easy in the half-sunken Mark Twain Steamboat in the bayou on the outskirts. Mickey can choose to either help them with pranking the locals or help the locals overcome their fears of the ghosts. If Mickey fixes the Pipe Organ while visiting Lonesome Manor, the ghosts will return home and give Mickey one of the missing pieces of Animatronic Donald.

Role in Ultima
In Ultima, the Lonesome Ghosts are forgotten characters who have joined the Circle of the Blot in order to let loose one hell of a scare upon the entire universe. Since they are ghosts, they cannot be killed or banished into the Underworld by physical methods, requiring magical means to put them in their place.
