This is the official Pac-Man cereal from the early 80s. This box is one of the later ones after they added Super Pac-Man marshmallows (the Super Pac-Man marshmallows were just bigger versions of the regular ones). At one point they included Ms. Pac-Man marshmallows as well, but the cereal didn’t have them at this time.

What Allee has to say about this:
Beyond anything, I love that two free gummi-worms were included in every box. Like how much extra did that cost General Mills?! And, as if this cereal needed to be more nutritious than it already naturally was.

Love all the background information on the Super Pac-Man marshmallows.

Is there still cereal in the box?
