Cheetos' original mascot was the Cheetos Mouse, who debuted in 1971 and disappeared around 1979. In 1986, Chester Cheetah was created by Brad Morgan, who art directed the commercials and designed the character, and Stephen Kane who wrote the original scripts for television commercials. The original 24-frame animation was done by Richard Williams. After Chester's introduction, the sly, smooth voiced cheetah began starring in more commercials and eventually became Cheetos' official mascot. He used the slogans "It ain't easy bein' cheesy" and "The cheese that goes crunch!" from 1986 to 1997, until it became "Dangerously cheesy!" from 1997 onward.
