"When they (Pikoi and others) passed outside of the islet of Mokapu, Pikoiakaalala again saw a rat on the cliff at Waimanalo. He shot at it and a man ran to see. He saw the rat struck just as Pikoiakaalala told them. The name of the rat was Kaulana-a-ka-iole and the place bears the name to this day.:
