One night, Nobita is sleep walking in a pink fog and wake up in the woods. In the dream Nobita saw talking animals. The next day, Nobita is talking to everyone but the experience “comparable to kindergarten dream” only to be mocked. Meanwhile, Nobita finds out a plan to turn the Hill behind into a Golf Course.
That night, sleepy Nobita realized that the Pink Fog is a door to enter the Animal Planet.
