Cap'n Crunch cereal was brought on the scene in 1963. One of the best-loved breakfast cereals of the western world, the brand is owned by the Quaker Oats company and is enjoyed by children and adults alike. Cap'n Crunch's primary (and in some cases, only) constituent is small golden puffs of sweetened corn and oats. Shaped approximately like overstuffed pillows, they are ostensibly intended to resemble treasure chests.
