Submarine 3: Rainbow Treasure

300 years ago, coastal residents could not bear the oppression and plunder of foreign colonial invaders, and formed pirates to fight against the colonists. The pirates snatched the colonists' treasures and buried them in a mysterious sea area. Legend has it that the mountains of treasures shone brightly and turned into beautiful rainbows. From then on, pirates and their treasures became famous as rainbows. Beaver Bobo (voiced by Xie Yuanzhen), who claims to be a descendant of the Rainbow Pirates, weaves the legend into a story and tells it to the undersea residents. As a result, he attracts the seahorse family who are unable to find the treasure and the ferocious and mysterious one-eyed shark (voiced by Tan Mantang). At the critical moment, Bobo was rescued by the small submarine Ali (voiced by Fan Churong). They took the small submarine Beibei (voiced by Hong Haitian) and the seahorse family on a journey to find the rainbow treasure. What will be waiting for this group of adventurers at the end of the vast ocean?
