The book repeatedly emphasizes that imagination is the foundation of all progress and problem-solving, as Jibby argues that everything from wagons to phonographs began with someone imagining them, and he uses creative thinking to outsmart others and solve mysteries.

Jibby demonstrates that careful observation and applied knowledge—such as noticing a bee's abdomen to find its hive or sniffing water to locate fish—are more powerful than brute force or luck, a lesson the other boys learn throughout the story.

The Riverbank boys initially tease Jibby but gradually form a close-knit group, working together to mine worms, hunt treasure, and solve problems, showing how cooperation and mutual respect build strong friendships.

The narrative is driven by the boys' quests—pearl diving, treasure hunting, and exploring rivers and creeks—reflecting a theme of youthful curiosity and the thrill of discovering the unknown.

Jibby, who is physically awkward and nearsighted, consistently outwits stronger or more aggressive characters like Wampus and the Tough Customer, illustrating that intelligence and strategy triumph over physical strength.

The Mississippi River and its surrounding environment are central to the story, serving as both a playground and a source of livelihood, with detailed descriptions of sand, mussels, fish, and wildlife highlighting a deep appreciation for the natural world.

The boys face numerous setbacks—flooded mines, bee attacks, and deceptive rivals—but persist through creative solutions, such as using a tree as a fishing pole or mining worms to earn money, underscoring the value of determination.

The boys initially try to deceive Jibby with tall tales, but Jibby's honesty and cleverness earn their trust, while antagonists like the Tough Customer and the Rat use deceit, showing how trust is built through integrity.
