Snap, Crackle and Pop

Snap,CrackleandPopare thecartoonmascots ofRice Krispies, a brand ofbreakfast cerealmarketed byKellogg'sand its successor companies.
The characters were originally designed by illustratorVernon Grantin the early 1930s.The names areonomatopoeiaand were derived from a Rice Krispiesradioad:
The first character appeared on the product's packaging in 1933. Grant added two more and named the trio Snap, Crackle and Pop.Snap is usually portrayed wearing achef's toque. Crackle often is shown wearing a red (or striped)tomte'stuqueor "sleeping cap", and Pop often wears adrum major'sshako, but is sometimes also seen with a chef's toque, or an odd combination of both a shako and a toque.Corporate promotional material describes their relationship as resembling that of brothers. Snap is the oldest and is known as a problem solver, Crackle is an unsure "middle child" and known as a jokester, and Pop is a mischievous yet also clumsy youngster and the center of attention.There was briefly a fourth gnome in the 1950s named Pow who represented the claimed explosive nutritional value of Rice Krispies.
From their original design as elderly gnomeswith large noses, ears and hats, Snap, Crackle and Pop were reimagined with younger and more proportional features in 1949. Some time after 1955, their elf-like oversized ears became more proportional yet pointed, as seen in commonportrayals of elves. They first appeared asanimatedcharacters in 1955, targeted toward such children's shows asThe Howdy Doody Show.The voices of the original gnomeswere provided byDaws Butler,Paul WinchellandDon Messick. More recent voices have includedKeith Chegwin,Chad Doreck,Eddie Deezen,Thom Adcox-Hernandez,Mona Marshall,Phil Vischer,Mike Nawrocki, andDino Andrade. As of 2009, the three gnomesare voiced by Andy Hirsch (Snap),Danny Cooksey(Crackle) and Mark Ballou (Pop).As of 2017, the three gnomes are now voiced byJosh Brener(Snap),Ben Schwartz(Crackle) andTom Kenny(Pop).
The trio were used in conservation messages duringWorld War IIand briefly re-imagined assuperheroesin the early 1990s, but later returned to their original gnome/elf-like form. In the 1950s – 1970's the characters were drawn by illustrator, Pete Eaton of Eaton and Iwen Art for Advertising.Leo Burnett Worldwideassigned Chicago-based cartoonist Don Margolis to do Snap, Crackle and Pop for the Rice Krispies boxes as well as other applications.Davidson Marketing also used him for their Rice Krispies assignments.

On 17 June 2020, former UK Labour politicianFiona Onasanyaquestioned why popular breakfast cerealCoco Popswas promoted with a monkey, while Rice Krispies used the white-skinned Snap, Crackle and Pop.
The original advertising jingle, "Snap, Crackle, Pop", was written by Nick Winklessunder the banner ofLeo Burnett Worldwide.  The lead sheet sent by Kellogg's lists the singers' names as Len, Hazel, and Joe. Nick's daughter said Nick's influence for the 3-part round wasFugue for TinhornsfromGuys and Dolls.
