    Don't let the poster with its kawaii characters fool you: "Chiikawa the Movie: The Secret of the Mermaid Island" has serious themes like murder, revenge, guilt and eternal torment! Sure, it's not as heavy as fellow animated film "Another World" (Hong Kong, 2025) but I'd not bring kids to see it!

    Chiikawa the Movie: The Secret of the Mermaid Island, my first exposure to Chiikawa is the McDonald's Happy Meal that I bought for my lil sis. An adventurous story that has amazing direction with its comedic timing, mystery, dark, joyful and sorrow moments to compliment the cute animal characters.
