While the exact roots of the switch are not publicly known, the Hanna-Barbera cartoon was the first case in which Clyde and Blinky behaved contrarily to how they were depicted in the arcade games. Here, Clyde was the self-proclaimed boss, Pinky was the "tough guy" of the group, Inky was wacky and erratic, and Blinky was cowardly. These characteristics also carried over into their facial expressions in the arcade game based off of the TV series, Pac-Land, where Clyde has angry eyes, Pinky has a standard expression, Inky has crossed eyes, and Blinky has timid-looking eyes.
In Pac-Mania, Blinky, Sue, Pinky, Inky, and Clyde return from Pac-Land, and their facial expressions return as well. However, in this game, the red ghost and orange ghost have their expressions switched from Pac-Land, and Namco Museum Volume 5's "How to Play" for Pac-Mania describes the red and orange ghosts respectively as such:
- Clyde - The Big Daddy of ghosts is bringing his henchmen.
- Blinky - A ghost with such an innocent expression.....
A few Japanese arcade flyers also showed Clyde as the red ghost and Blinky as the orange one, and in this game, the red ghost and orange ghost are referred respectively to as "CLYDE" and "BLINKEY [sic]" internally.
Namco Classic Collection Vol. 2 and beyond
Namco Classic Collection Vol. 2 was the first game to feature this change in-game, for both the original and Arrangement versions of Pac-Man. At the title screen for either game, the four main ghosts are organized as shown on the image to the right.
- While this was eventually corrected in the Pac-Man series itself, when closed captioning is put on in the movie Wreck-It Ralph, the captions refer to Clyde as Blinky.
