The giant serpent is the antagonist of the Bunun deluge myth, one of the most widely recorded narratives of the tradition alongside the sun-shooting story. Its coiled body blocked a great river — in central-Taiwan versions the Zhuoshui River — and the impounded waters rose until only the highest peaks, such as Yushan and Luntou-shan, stood above the flood. The ancestors of the Bunun took refuge on the summits until a giant crab fought the serpent and sliced open its belly, whereupon the dead serpent washed away and the waters drained. Japanese-era linguists Ogawa Naoyoshi and Asai Erin recorded versions of the tale in Bunun in 1935, and Ho Ting-jui's comparative survey of Formosan mythology (1971) analyses it among the island's flood myths caused by a blocking monster rather than by rain.
