Tears streaming down his face, Nobita said a bittersweet goodbye to Kibo. They had saved the world, but Nobita was losing a dear friend. Kibo smiled, promising that as long as humans cared for trees and protected the Earth, they would always be connected.

The raging energy of the Green Giant began to subside, replaced by a soft, warm glow. The giant transformed into a massive, beautiful tree of life, restoring balance to both worlds. The threat was over, but at a cost. Kibo had fulfilled his destiny and had to remain on the Green Planet to help guide his people towards a peaceful future.

Nobita and his friends were horrified. They knew that humans had made mistakes, but they also knew that love, compassion, and the desire to protect the environment existed in human hearts. They pleaded with Princess Rire and the elders, but their cries fell on deaf ears. The plant people saw humans as a virus that needed to be eradicated.

But their peaceful days were short-lived. One day, while playing in the woods, a mysterious vortex of green light opened in the sky, swallowing Nobita, Kibo, and their friends. They were pulled through space and time to the Green Planet, a world inhabited by advanced plant beings who had evolved far beyond the flora of Earth.

Once upon a time, in a quiet neighborhood in Japan, a young boy named Nobita Nobi sat in his room with a mountain of homework and a heart full of frustration. He felt small, powerless, and constantly overwhelmed by the expectations of the grown-up world. But Nobita was not an ordinary boy; he had a secret weapon, a best friend from the future named Doraemon, a robotic cat with a 4D pocket full of wonders.
