As James ventured deeper into the magical world of the giant peach, he encountered a whimsical dictionary of words he had never heard before. Words like 'bibliopole' meaning a dealer in books, 'guddle' which described the act of catching fish with one's hands, and 'rumbustious' to portray someone or something as noisy and full of energy. These newly discovered words filled James with a sense of curiosity and wonder, urging him to explore further into the enchanting world within the peach.
