Doraemon: Nobita's Great Adventure in the Antarctic Kachi Kochi

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.

Doraemon and Nobita decide to build a perfect toy robot. However, their creation turns out to be a little more uncanny than an object of appreciation and wonder.

Nobita and Doraemon use time tree Mochi and catch a big bird, which has been extinct for 500 years ago. To protect the animal, Nobita and Doraemon go to Beremon Island, overseen by a golden beetle named Herakles.

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.

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.
