The names of the green and gray pac-man ghosts Blinky, Pinky, Inky and Clyde are the primary group of fictional ghosts
Clyde is the orange ghost in the original Pac-Man. In Ms. Pac-Man, Clyde is replaced by Sue (also orange). In Pac-Man Jr, Clyde/Sue is called Tim. Although it's not a "replacement" per se, it's also interesting point that the original Pac-Man ghosts have their own nicknames within that game: Inky, Pinky, Blinky, and Clyde are also called Bashful, Shadow, Speedy and Pokey, respectively.
There's Mr. & Mrs. Pac-Man, for the Pac's. The ghosts are Blinky (red), Pinky (pink), Inky (sky blue), & Sue (lt. Orange). Down the years, different versions of Pac-Man came out, and in a game called PAC & Pal, there's a green baby ghost called Muri.(I think that's how you spell it)
