Doraemon Movie 11: Nobita to Animal Planet

A strange pink mist leads Nobita into a distant world inhabited by intelligent animals. There he meets the dog-like boy Chippo and discovers a peaceful civilization where animals live much like humans, protected by beliefs surrounding their moon and the planet's unusual history.

The peace is threatened by the Nimuges, invaders from a polluted neighboring world who intend to seize the animal planet for themselves. When Nobita returns with Doraemon, Shizuka, Gian, and Suneo, their accidental visit becomes a fight to protect Chippo's home from a force willing to destroy another world after ruining its own.
