<P> The two arrive at Te Fiti's island, only to be attacked by Te Kā, who damages Maui's fishhook . Fearful he will lose his power, Maui abandons Moana, who tearfully asks the ocean to find someone else to restore the heart . The ocean obliges and takes the heart from Moana . Tala's spirit appears, inspiring Moana to find her true calling . Moana decides to fulfill her destiny, retrieves the heart, and sails back to confront Te Kā . Maui returns, convinced by his tattoo to change his mind, but his fishhook is destroyed by Te Kā . Moana discovers Te Fiti is missing, but realises Te Kā is Te Fiti without her heart . Moana restores Te Fiti's heart, transforming her back to normal; Te Fiti then heals the ocean and islands of Te Kā's poison . Maui apologizes to Te Fiti, who forgivingly restores his fishhook and goes into a deep sleep . Moana bids farewell to Maui, returning home where she reunites with her parents and takes up the role of chief, setting sail on a voyage, accompanied from afar by Maui (in a form of a giant hawk) and Tala (in the form of a manta ray). </P> <P> In a post-credits scene, Tamatoa, stuck on his back, addresses the audience, knowing they would help if he was named Sebastian and sang in a Jamaican accent (making reference to The Little Mermaid). </P> <Ul> <Li> Auli'i Cravalho as Moana, the 16 - year - old daughter of village chief Tui and Sina, who is chosen by the ocean to restore the heart of Te Fiti <Ul> <Li> Louise Bush as a younger Moana </Li> </Ul> </Li> <Li> Dwayne Johnson as Maui, a legendary shapeshifting demigod who sets off with Moana on her journey </Li> <Li> Rachel House as Tala, Moana's grandmother .
