Jong Batu is a rock outcrop located in the Brunei River. It is shaped such that when viewed from the shores of the Brunei River, it resembles a sinking ship, with the bow sticking out of the water. In Brunei folklore, the legend of Nakhoda Manis (literally the "Captain Sweet" in Malay) tells of how an unfilial son was turned to the rock outcropping known as Jong Batu.
