Cap'n Crunch is a product line of corn and oat breakfast cereals introduced in 1963 and manufactured by Quaker Oats Company, a division of PepsiCo since 2001.
Appearance[]
Since the Jade Key challenge in the movie is The Shining challenge, the Captain Crunch only appears in the Jade Key challenge in the book; not the movie. The Captain Crunch Cereal Box includes a whistle toy that is mentioned in this poem:
The Captain conceals the Jade Key
in a dwelling long neglected
But you can only blow the whistle
Once the trophies are all collected
In the film a Halliday Scholar can be seen examining a photo of a Cap'n Crunch Bubbleyum cereal box on his computer.
The same box appears on a shelf when Wade is choosing outfits in the garage.
