Doraemon: Nobita and the Platinum Labyrinth

It's spring break again, and Nobita agrees to go to the "Platinum Hotel" for sea bathing with his father. Nobita was very happy at first, but then he searched all travel agencies and found no such hotel. And a mysterious suitcase was delivered to Nobita's home, and Nobita came to the Platinum Hotel through this suitcase. Nobita and Doraemon were playing happily on the island, but Doraemon suddenly disappeared. It turned out that Doraemon was carried away by a mysterious rocket. Later, Nobita met Sabio. It turned out that Sabio was a spaceman from the Chamocha planet, and Doraemon was taken away by the robot army. In order to save Doraemon, Nobita decided to go to the Demon Chasing Star and challenge the dictator Nabo Gistler I.
