Pink Panther Flakes
Post’s Pink Panther Flakes were conceived as a 1972 tie-in with The Pink Panther Show, an animated Saturday morning offering. One popular feature of the cereal was its ability to turn milk instantly pink as soon as it made contact with the flakes.
This could be found on the back of the box: “Have breakfast with the Pink Panther! Pink Panther Flakes are pre-sweetened, pink frosted corn flakes. They’re fun to eat, good tasting and fortified with 8 essential vitamins. Try ’em. You’ll love ’em…”

Nintendo Cereal System
It wasn’t around for long after it popped up in 1988, but Nintendo Cereal System came bouncing into the crowded kids’ breakfast market with Mario and Zelda as its secret weapons. Oh, and its ‘fruity’ and ‘berry’ natural flavors.
Zelda and Mario also had their own individual cereal in the same box. Two bags holding the multi-colored offerings were included, with the idea being kids could get creative with however they wanted to mix them together.
