Walton Chunky is the inventor of Breakfast Chunks, a hard cereal made out of compressed grain. The idea for Breakfast Chunks first came to him when he was working at a garbage dump, compressing cars, and he found a big sack of bran next to him. Molding a handful of the stuff into a cube, he became inspired to create the aforementioned cereal brand. His sole appearance was in the episode "Bad, Bad Rubber Piggy".
