Doraemon: Nobita and the Animal Planet

Nobita (Noriko Ohara) wants somewhere to go that is not school or home, and Doraemon (Nobuyo Oyama) is never short of a gadget. Then a pink fog seeps into his house, and he and his friends Shizuka, Suneo and Gian wake up on a planet of animals. Tsutomu Shibayama sends them to work alongside the natives to trace the fog, and the story keeps asking how people and animals share a world.
