Echo is a youngster who can't quite decide if it's time to grow up and take on new responsibilities-or give in to her silly side and just have fun. Dolphin society is tricky, and the coral reef that Echo and his family call home depends on all of its inhabitants to keep it healthy. But Echo has a tough time resisting the many adventures the ocean has to offer. 　　译文(2): Echo 是一个年轻人，她无法决定是该长大，承担新的责任，还是屈服于自己愚蠢的一面，享受生活。海豚的社会很复杂 Echo 和他的家人称之为家的珊瑚礁依赖于所有的居民来保持它的健康。但是 Echo 很难抵抗海洋带来的冒险。
