Doraemon: Nobita's South China Sea Adventure

Nobita and his classmates went to the library to find information about the sea for their summer homework. After accidentally seeing the book "Treasure Island", they felt longing for treasure hunting, so they accidentally spied on Treasure Island through Doraemon's prop "Treasure Map". So Nobita and Doraemon encouraged Fat Tiger, Xiaofu and Shizuka to join this adventure and set out for Treasure Island. After arriving on the island, in order to increase the atmosphere, Doraemon took out the "Legend Restoration Machine" to add an adventurous atmosphere. But for some unknown reason, time and space suddenly caused a change. The time and space chaos moved them to the Caribbean in the 17th century, and they were involved in a fight between pirates. Not only was Nobita separated from everyone, but Doraemon even lost his fourth-dimensional pocket. In the chaos, Nobita was rescued to the island by the pink dolphin "Luffy", and got acquainted with the boy "Jack" who lived alone on the island. On the other hand, Doraemon and his friends were rescued by "Captain Git", a contemporary pirate across seven seas, and "Betty", the daughter of his friend "Captain Colter". With their help, they went to the legendary treasure island to rescue Nobita. Later, it was also discovered that Treasure Island was the secret base of "Dr. Cologne" and "Kashu" in the future world. They were a group of evildoers who transformed creatures into violent traits for sale on Treasure Island. Can Doraemon and Nobita successfully meet up? Can they stop Cardiff's criminal group's plan?
