Crunch

Crunch, commonly known as Crunch cereal, is a corn puff breakfast cereal popular among children. When their father is unable to cook healthier food due to time, Arthur and D.W. will eat the cereal.

Crunch cereal is produced by the Crunch Cereal Company, which also runs promotional contests. Jack is a known employee of the company.

The Crunch Cereal Jingle Contest
The Crunch Cereal Jingle Contest was held in the winter. Participants were asked to write a jingle that would be aired on a new TV commercial. All entries had to be sent in with 20 box tops. The winner would receive a year's supply of Crunch cereal.
