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. In the story, the gum has not yet been perfected, but Violet Beauregarde tries some anyway, which turns her into a giant human blueberry.

Wonka shows them three-course dinner chewing gum in the Inventing Room and Violet Beaugarde takes the gum out of Wonka's hand and sticks it in her mouth. Her father asks her how it tastes, and she says, "It's amazing, it's made of tomato soup, roast beef and baked potato, and blueberry pie." Violet blows up to a blueberry, and her father tells Mr. Wonka to call a doctor. Mr. Wonka seemingly blames himself for not getting it in the 2005 film.
