Doraemon: Nobita’s Dinosaur

Suneo flaunts a fossil and excludes Nobita, which fuels Nobita's determination to prove there is a living dinosaur. He loudly declares that he will find one, no matter what. The idea consumes him as he plots a plan to make it happen.

A landlord punishes Nobita for disturbing the hillside; he is forced to dig a hole as punishment. The burden is heavy and the moment underscores Nobita's reckless ambition. The hillside becomes the unlikely starting point of an unbelievable discovery.

On the hillside, Nobita uncovers an egg-shaped stone. He uses a time wrap to restore it to its former form and then warms it to hatch Piisuke. The hatchling dinosaur solves Nobita's problem of proving he can find a living one.

Nobita chooses not to reveal Piisuke immediately and begins to let it grow. He also negotiates with friends and plans to wait before presenting proof. The fragile plan sets the stage for a larger adventure.

Piisuke grows too large to hide now, so Nobita and Doraemon conceal him in a nearby lake. Their secrecy is short-lived when a mysterious assailant from the 24th century appears, eager to buy Piisuke. The stakes rise as the hunter's interest becomes a threat.

To protect Piisuke, Nobita and Doraemon transport him to the Late Cretaceous, about 100 million years ago. They are briefly pursued by the assailant but manage to escape intact. The journey marks the beginning of a perilous prehistoric odyssey.

Back in the present, Gian, Suneo, and Shizuka confront Nobita about his claim. Nobita tries to prove it, but their skepticism prompts him to take them to his house to show Piisuke. The lack of proof strains their friendship and raises tensions.

With no physical proof, Nobita uses a TV monitor to show Piisuke, hoping to convince them. However, he later realizes Piisuke has been unknowingly transported to the North American shore when the time machine is attacked. The discrepancy pushes them toward a new quest.

The group travels to the North American shore to retrieve Piisuke, hoping to bring him back with them. The time machine is overloaded and destroyed on arrival, leaving them stranded. They must find another way home and locate Piisuke in the new setting.

They finally locate Piisuke on the North American shore and apologize for their doubt. Doraemon quietly considers repairing the time machine but reveals it is broken and must be taken back to Nobita's desk in Japan to fix. The emotional reconciliation comes as they prepare for more challenges.

A Tyrannosaurus emerges from the forest during a beachside dinner and threatens their progress. Doraemon uses the Momotaro Dango to control the beast and orders it to return to its tasks. The dinosaur becomes a tool in their plan to return home.

They journey across the ancient land bridge of Beringia, meeting friendly giants like Brontosaurus and fast Ornithomimus. The group also faces aerial attacks from Pteranodons that topple their bamboo copters. The landscape is a perilous maze of wonders and hazards.

Dinosaur hunters from the 24th century reveal themselves and chase Piisuke and the others. Gian, Suneo, and Shizuka are captured in a cliff-side ambush while Nobita, Doraemon, and Piisuke slip away. The hunters push hard to reclaim Piisuke for their master.

To shake off pursuit, they lure the hunters with mud statues and escape across a river on a raft. The plan backfires when Gian, Suneo, and Shizuka are used as bait and fall into danger. The group regroups after a narrow escape.

Nobita and Doraemon rescue Gian, Suneo, and Shizuka, and the Time Patrol finally captures the hunters. Piisuke is transported back to Late Cretaceous Japan, ending his journey there. Nobita and his friends bid Piisuke farewell and return to the present.
