Tuna actually lived in peace in Māui’s home for some time. But one day, Tuna challenged Māui to a duel. Each would take a turn leaping into the others’ body and trying to kill him. If Tuna killed Māui, then Tuna would take his wife back. Tuna’s turn came first: he made himself small and entered Māui’s body. When he came back out, Māui was intact. Now it was Māui’s turn: Māui made himself small and entered Tuna’s body, tearing it apart. Māui cut off Tuna’s head and, at his mother’s suggestion, buried it in a corner of his house.
