Duan asked his mother sadly: "Mom, why do my brothers and sisters and I look different?" The fish mother always comforts it: "Because you are a special gift from the King of the Sea to mother!" But its good friend Ah Gui said: "Ah Dai, maybe you are not a tropical fish?" Yes, could it be another small fish that mother picked up? So Dumb decided to find his real family!

Dui encountered many crises: plastic bags affect the survival of fish, human oil flows into the sea and affects fish life, and there are ubiquitous fishing nets and cans. There are many ocean crises... Can Dumb find his family? What secrets does it have? Purpose: Protect the marine environment
