Jerome or J is the narrator of the story and appears to be a happy go lucky man. He has varied shades to his character. At first, he is a hypochondriac who thinks that he has all the diseases of the world. He likes to be at the head of the things, which is clear from his behaviour when they pack for the boat trip. He is also fond of animals and shows considerable knowledge about the things around him. Like his two friends, he is also vain, but more sensible and practicle.
