Doraemon: Nobita and the Castle of the Undersea Devil

As Nobita, Gian, Shizuka, and Suneo are making their own space movie, a fleeing bug-sized alien president makes his way to Earth, and needs the help of the kids and Doraemon to stop an oppressive dictatorship threatening his democracy.

When Suneo does not show Nobita the fossil of a dinosaur claw, he takes up a challenge to find a dinosaur. He digs up a hillside and finds an egg, which later hatches and becomes a dinosaur.

Shizuka ends up in the fantasy world of the 'Arabian Nights' story. However, Doraemon, Nobita, Suneo, and Jyaian must find her from the imaginary Middle East and bring her back to the real life.

After a typhoon hits Nobita's town, he and Doraemon discover a wind sprite who, with some help from Doraemon's 22nd-century tech, takes them and their friends to a fantastic world of wind and storm people. But the wind sprite, named Fuuko by Nobita, had brought them to her world for a reason, as her peoples' gods are battling, and Suneo might be a key player in their feud.

During summer vacation Nobita picks up a small rocket containing Papi, a palm-sized alien president escaping rebels on his home planet Pirika.

Nobita finds a passage to a spaceship in another dimension. With their new friends, he and Doraemon fight the cruel leader of an exploited planet.

Nobita and his friends find a portal to a mysterious resort filled with metal buildings. They soon discover that the person who opened the portal for them has an ulterior motive.

A sapling Nobita discovers is turned into a plant-boy with help from Doraemon, and becomes Earth's only hope at passing judgment from the dryadic aliens of the Green Planet.
