The Big O Show takes place at a large structure visible from the side of Utop Marina Hotel in Yeosu, using fountains, lighting, and lasers. Water shoots up between the structure's sections while music, fire, and lasers accompany a "Hana Show" themed around the ocean environment. Tickets are available through Naver Reservation, with P seats in the center and S seats on the outside, and the first three rows get wet when it rains. The opening 15 minutes are worth watching, but the story and music have remained the same for about ten years, making it dated content aimed mainly at children.
