Grandpa Joe offers to accompany Charlie on the tour, but Charlie explains how he was offered money for the ticket and intends to sell it. Grandpa George (David Morris) reminds Charlie that money is far more common than the tickets, and convinces Charlie to keep it. The visitors find Wonka to be peculiar, lonely and acting odd at the mention of "parents". The tour shows how fantastical the factory operates under the efforts of the short humans called Oompa-Loompas. The other four children succumb to temptation, and end up being caught in the factory workings and have to be safely recovered by the Oompa-Loompas, albeit in worse shape than at the start of the tour: Augustus falls into a river of chocolate and has been sucked up by a pipe before being rescued from the fudge processing center; Violet expands into an oversized blueberry when she tries an experimental piece of chewing gum; Veruca is thrown away as a "bad nut" by trained squirrels; and Mike is shrunk down to a few inches in height after being the first person transported by Wonka's new television advertising invention.
