Raven is the father, Koukou the mother, Hat and Bat the sisters, and Pikoiakaalala the brother of the rat family of Wailua, Kauai, who change into human beings. The sisters marry men of note. Pikoiakaalala wins in his first attempt to float the Koieie board, then follows it down the rapids and swims to Oahu. Here he beats Mainele, the champion rat shooter, by summoning the rats in a chant and then shooting ten rats and one bat at once. Then he defeats him in a riddling contest in which the play turns upon the word rat. On Hawaii the king, Keawenuiaumi, wants the birds shot because they deceive his canoe builders and prevent any trees from being felled. Pikoiakaalala succeeds in shooting them by watching their reflection in a basin of water.
