Pretty Cure Miracle Universe

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.

The Straw Hats visits an island, known as Mecha Island, where a fisherman sings an old folk song about a Golden Crown. Searching for that mysterious treasure, they find a hidden entrance into the island. The island's leader, Ratchet, impressed with the find and in search of the Golden Crown himself, invites the crew to join him in his search and the crew along with Ratchet and his henchmen enter the cave. As it turns out, the islands true form, is that of a giant turtle. Ratchet, who had known this all along, uses his mechanical castle to take control of the turtle, in order to use it, to take over the world. Now the Straw Hats have to stop not only Ratchet, but also the helpless turtle, from crashing into a nearby island.

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

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.
