Doraemon: Nobita’s Dinosaur

Nobita was punished for disturbing the hillside while searching for a dinosaur. After Suneo mocked him by showing off a fossil, Nobita loudly declared he would find a living dinosaur and began digging recklessly. A landlord caught him and forced him to dig the hole as punishment.

Nobita discovered an egg-shaped stone on the hillside where he was punished. He used Doraemon's time wrap tool to restore the stone to its original form, then warmed it with his hands. This caused the egg to hatch, revealing Piisuke the dinosaur.

The egg-shaped stone was buried in the hillside where Nobita was digging, linking his punishment to his discovery.

The hunter from the 24th century wanted to capture Piisuke to sell him. In the future, living dinosaurs are extremely rare and valuable, making Piisuke a profitable target for illegal collectors.

They transported Piisuke to the Late Cretaceous, about 100 million years ago, to protect him from the 24th-century hunter. The past was the safest place because time travelers from the future could not easily hunt there without being detected by the Time Patrol.

When Nobita and his friends arrived at the North American shore looking for Piisuke, the time machine was overloaded and destroyed on arrival. This left them stranded in the present-day outside Japan with no way to return home.

During a beachside dinner, a Tyrannosaurus emerged from the forest and threatened the group. Doraemon used the Momotaro Dango, a special tool that allows its user to control dinosaurs, to command the T-Rex to return to the forest and stop attacking them.

The Time Patrol is an organization from the future that enforces laws against illegal time travel and poaching prehistoric creatures. They finally intervene at the end of the movie, capturing the 24th-century hunters who were chasing Piisuke and the group.

Piisuke was transported back to Late Cretaceous Japan because he belonged in his own time period. The Time Patrol ensured he was returned safely, and Nobita and his friends had to say goodbye, knowing it was the right thing for Piisuke's survival.

During the river escape, Gian, Suneo and Shizuka were used as bait by the hunters and fell into danger. Nobita and Doraemon managed to rescue them from the cliff-side ambush, and the group reunited before returning to the present.

Nobita was motivated to prove he could find a living dinosaur after Suneo mocked him by showing off a fossil and excluding him. The embarrassment fueled Nobita's determination to show everyone he could actually discover a real, living dinosaur.
