Corrected entry: Small contradiction: Wonka flips when the boy drinks from his chocolate river and later even falls into it. Wonka is angry given the contamination of his chocolate, however a few minutes later he happily takes the whole lot on a boat on that same river, a boat on which people even become seasick. Enjoy your bar Mr. Wonka.
Corrected entry: On Charlie's birthday, the two grandpas get him a Wonka, but it isn't a Wonka bar. Why would they think that a golden ticket was in it when Charlie fools them, because the tickets were hidden in Wonka bars?
