Professor Phineas Plump is one of the Hitchhiking Ghosts character for The Haunted Mansion. The Hitchhiking Ghosts are three resident spirits of the Haunted Mansion known as Phineas (aka the Traveler), Ezra (aka the Skeleton), and Gus (aka the Prisoner). As hitchhiking spirits they use their ghostly powers to haunt mortals that cross paths with the mansion, working to fill up a quota from mansion officials.

In all versions of the ride (except Phantom Manor and Mystic Manor), the trio appear in the exit crypt to haunt guests as they leave the mansion as the Ghost Host explains their nature. Each of the ghosts appear alongside the guests in mirrors showing their Doom Buggies.
