The Three Course Dinner Chewing Gum was a piece of gum invented by Willy Wonka that feeds a person almost like they're really eating dinner, starting with tomato soup, roast beef, and baked potato before concluding with blueberry pie and ice cream (though any soup, appetizers, main courses, etc. could be used). However, it's currently in development, and has major flaws with it, most notably with the Dessert Course consisting of Blueberry Pie with Ice Cream. At the Dessert Course, the Gum will transform the chewer into a gigantic blueberry, just as it did to Violet Beauregarde.
Appearance in the Film[]
In the film, Wonka shows the tour group a machine in The Inventing Room. Wonka pulls a lever on the machine and a few seconds later the gum is produced. Violet Beauregarde grabs the gum and consumes it, ignoring Wonka's warning that it wasn't complete; as a result, Violet starts being affected by it during the Dessert Course. She gradually turns completely blue and inflates into a giant 10-foot blueberry due to the Blueberry Juice from the Blueberry Pie. Fortunately for Violet, she was then extracted of all the Blueberry Juice at the Juicing Room, but was left completely blue afterwards as she and the rest of the guests left.
It is unknown if Willy Wonka is still working on the Gum to be finalized for sale.
