The underlying mood of the story is fun, that is a result of a purposeful adventure. It takes a mischievous tone when Jim plans to explore the island alone and when he decides to free the Hispaniola of its anchor. It also includes moods such as sorrow when Jim’s father and Captain Billy Bones die, and fear when Jim faces Long John Silver after the incident in the apple barrel, when he sees Ben Gunn, at sea, and when he is captured by Long John’s men.
