They crew spot an uncharted island, which Sinbad encourages the captain to approach, hoping that it holds untold riches.
Sinbad, Habeeb and two other sailors take a rowboat to the island, which has a strange appearance: it is flat and bare, with no grass, trees or sand.
The island shakes violently, and the two sailors return to Captain Aziz's ship, leaving Sinbad and Habeeb behind.
That night Sinbad reveals to Habeeb that he doesn't want to marry the king's daughter, and will leave the island in order to avoid fulfilling his promise.
Habeeb and Sinbad sneak out of the castle by hiding in crates that are to be delivered to Captain Aziz as supposed presents from King Jamal.
