Inventing Room

The Inventing Room is Willy Wonka's favorite and most secret room. It holds all of his newest inventions and candy that still needs testing, examples being the Everlasting Gobstoppers, Hair toffee, and the Three Course Dinner Chewing Gum.

The room is a gigantic laboratory filled with machines that create candy, most notably the gum machine. Above the room, a giant catwalk allows the Oompa-Loompas to traverse atop the machines, accessing the controls of many machines and the room as a whole.

It also has a major role where Violet Beauregarde turns into a blueberry. The room has the three course chewing gum dinner.
