re: An extremely exhaustive look at symbolism in Willy Wonka and the Chocolate Factory

Good question. I guess if I had to give some sort of symbolic reason I'd say because at that point Charlie and Grandpa Joe are only able to see half the truth, because Wonka hasn't revealed the other half yet. Honestly, though, that seems a trifle too on-the-nose for me, and I think it may simply be a case of "schnozberries tasting like schnozberries." In other words, a whimsical but meaningless detail in something that is, after all, still a kids' movie.
