Violet Beauregarde brings this to life in the film adaptations of Charlie and the Chocolate Factory. It's not so much from stuffing herself as it is from a problem with the final part of the three-course-meal gum. The blueberry pie part quite literally causes the unfortunate victim to become a blueberry! The gum itself is the size of a regular piece of gum. There's a reason why Wonka hadn't released it to the public yet!
A literal case was shown in The Master of Disguise. One of Pistachio's disguises while being trained by his grandfather was an inflating "fat businessman" suit. Unfortunately, Pistachio tugged on the cord too hard and, well, guess what happens next.
