How about, "Kauila".
According to Hawaiian legend, Kauila was a turtle with special power. She could turn herself into a young girl. The people of Ka'u loved Kauila because her spring gave them drinking water. They loved her even more because during the day, Kauila took human form and watched over their children as they played along the shoreline of the bay. She did this because she, too, liked to play.
Kauila kept the children safe.
