Snap, Crackle and Pop the early 1990s, but later returned to their original elf-like form. Likewise, there was briefly a fourth gnome in the 1950s named Pow who represented the claimed explosive nutritional value of Rice Krispies. Leo Burnett Worldwide assigned 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. Don did the three gnomes until the end of 1998. "Snap", "crackle" and "pop" are terms, based on the Rice Krispies mascots, used for the fourth, fifth and sixth time derivatives of position.
