The bulk of the cereal, which first hit the market in 1983, was made up of orb-shaped sweetened corn puffs that looked a bit like Pac-Man himself, without the missing slice that is his mouth. To sweeten things further, the cereal was studded with colorful mini marshmallows in the shape of Pac-Man and the ghosts from the game - Inky, Blinky, Pinky, and Clyde. Some later iterations of the cereal also featured marshmallows in the shapes of both Ms. Pac-Man and a larger Super Pac-Man.
