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.

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.

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.
