Wigan's first son Kabigat went from Hudog (the Sky World) to Earth World to hunt with his dogs, but the earth was then entirely flat, causing no echoes by which he could hear his dogs barking. He mused a while, went to the Sky World, and came back with a large cloth with which he closed the exit of the rivers to the sea. He returned to Hudog and told Bongabong what he had done. Bongabong had Cloud and Fog go to the house of Baiyuhibi, and Baiyuhibi brought together his sons and bade them rain for three days, stopping finally when Bongabong commanded. Wigan told Kabigat to remove the stopper. When he did so, the waters which covered the earth formed mountains and valleys as they rushed out. Bongabong called on Mumba'an to dry the earth.
