Moana 2 has a mid-credits scene that sets up the franchise’s future, but it may not have been the original direction. The titular Polynesian princess returns to the big screen, where she faces a powerful god Nalo, who sinks the island of Motufetu to disconnect the tribes from each other. Despite overcoming him at the end of Moana 2, the mid-credits scene reveals that Nalo wanted revenge against Moana (Auliʻi Cravalho) and Maui (Dwayne Johnson).
