Question: When Dorothy picked an apple off a tree, she was reproved by the tree himself. And the Scarecrow says, "It's just that she doesn't like little green worms." What does he mean by that?
Answer:He's tricking the tree by insulting it so that it will become angry and retaliate by throwing the apples at them, which it does, and Dorothy can then eat them, which was the intent all along.
Chosen answer: He's insulting the tree by saying its apples are infested with worms.
