Bisangolan ("the place of opening or tearing") is a gigantic spirit, who lives near the river, and who in time of floods uses his head-axe and walking-stick to keep the logs and refuse from jamming. "He is very old, like the world, and he pulls out his beard with his finger nails and his knife. His seat is a wooden plate." He appears in the Dawak, Tangpap, and Sayang ceremonies, holding a rooster and a bundle of rice.
In Ba-ak he is called Ibalinsogóan, and is the first spirit summoned in the Dawak ceremony.
