Doraemon: Nobita and the Animal Planet

One night, Nobita enters an unfamiliar forest through a pink mist (later revealed to be 22nd-century random gas, which the animals call the Staircase of Light). In this forest, animals communicate using human language and walk upright. The next day, Nobita tells his classmates about his experience, but they laugh and say he is "dreaming up a fairy tale world." Even when Nobita shows them a flower he brought back from the dream, no one believes him. Meanwhile, developers plan to build a golf course on the nearby hillside. That night, Nobita enters the forest again, discovering that it was not a dream but an actual planet inhabited by animals. There, Nobita and Doraemon meet Chaminbo and become good friends. The next day, those planning to flatten the hillside begin their survey work. Although Doraemon uses gadgets to drive them away, they remain undeterred. Later, Shizuka follows Nobita through the mist to the animal planet, while Suneo and Gian, who secretly follow them, end up on the planet Remori. A great adventure begins...
