Snap, Crackle and Pop are the cartoon mascots of Rice Krispies, a brand of breakfast cereal marketed by Kellogg's and its successor companies WK Kellogg Co and Kellanova.
History
The characters were originally designed by illustrator Vernon Grant in the early 1930s.[1] The names are onomatopoeia and were derived from a Rice Krispies radio ad: "Listen to the fairy song of health, the merry chorus sung by Kellogg's Rice Krispies as they merrily snap, crackle and pop in a bowl of milk. If you've never heard food talking, now is your chance."
The first character appeared on the product's packaging in 1933. Grant added two more and named the trio Snap, Crackle and Pop.[1] Snap is usually portrayed wearing a chef's toque.
