Breakfast Pals (1939)

In this promotional cartoon for Rice Krispies breakfast cereal, two young boys are eating breakfast one morning and one complains about how "mushy' his cereal is. Suddenly Snap, Crackle and Pop--one of the boys' "breakfast pals"--show up to replace the mushy cereal with fresh, crispy Rice Krispies. However, the "Mushy" gang shows up to prevent them from doing so, and a fight ensues, with the Breakfast Pals triumphing and the boys wind up eating their Rice Krispies, as God intended.
