I was a character designer and animator on these advertisements for Kellogg's Extra. 
Below are some examples of my initial character design exploration. Experimenting with different ways to give personality to cereal clusters with such irregular shapes. After settling on a style, I was asked to draw up some design guidelines and style frames for myself and the other animators to reference during production.
