In Charlie and the Chocolate Factory, Wonka has hidden five Golden Tickets inside chocolate bars. The finders are rewarded with a tour of his factory (with an adult of their choice) and a lifetime supply of chocolate. The children are unaware, though, that the tour is also a competition to test their character. As the tour proceeds, four of the children are eliminated, leaving Charlie Bucket the winner. At this point Wonka reveals that the real prize is the factory, as Wonka needs someone to take it over and look after the Oompa Loompas who work there.
