With the help of Doraemon, the pair travel to the moon and create bunnies that will build their own colony. After he returns, Nobita tells his class about their adventure but no one will believe him. That is until a new student and his sister arrive who appear to come from a very far away place.

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.

When Nobita goes diving with Doraemon, a mermaid named Sophia comes close to him and they all befriend her. When they proceed towards her kingdom, they encounter a fight between two opposing tribes.

Upon hearing about the story of Treasure Island, Nobita dreams of discovering and exploring his own treasure island, despite the fact all of the Earth has been mapped already.

One day during summer vacation, a palm-sized alien named Papi appears from a small rocket that Nobita picks up. He is the president of Pirika, a small planet in outer space, and has come to Earth to escape the rebels. Doraemon and his friends are puzzled by Papi’s small size, but as they play together using the secret tool “Small Light”, they gradually become friends. However, a whale-shaped space battleship comes to earth and attacks Doraemon, Nobita and the others in order to capture Papi. Feeling responsible for getting everyone involved, Papi tries to stand up to the rebels. Doraemon and his friends leave for the planet Pirika to protect their dear friend and his home.

Sewashi and Doraemon find themselves way back in time and meet Nobita. It is up to Doraemon to take care of Nobita or else he will not return to the present.
