dog transformation

He was not famous for inventions, but he was always ready to improve upon anything which was already in existence. He could take the sun in hand and make it do better work. He could tie the moon so that it had to swim back around the island to the place in the ocean from which it might rise again, and go slowly through the night.

His brothers invented a slender, straight and smooth spear with which to kill birds. He saw the fluttering, struggling birds twist themselves off the smooth point and escape. He made a good light bird spear and put notches in it and kept most of the birds stuck. His brothers finally examined his spear and learned the reason for its superiority. In the same way they learned how to spear fish. They could strike and wound and sometimes kill--but they could not with their smooth spears draw the fish from the waters of the coral caves. But Maui the youngest made barbs, so that the fish could not easily shake themselves loose. The others soon made their spears like his.

The brothers were said to have invented baskets in which to trap eels, but many eels escaped. Maui improved the basket by secretly making an inside partition as well as a cover, and the eels were securely trapped. It took the brothers a long time to learn the real difference between their baskets and his. One of the family made a basket like his and caught many eels. Then Maui became angry and chanted a curse over him and bewildered him, then changed him into a dog.
