A mysterious pink fog takes Nobita, Doraemon, Shizuka, Suneo, and Gian to a planet populated by animals. Legend says that the ancestors of this population used to live on the moon, but were transported out of there to escape from the voracious creatures that lived there too.

It's a thrilling, action-packed entertainer with sparks of men versus villains in an up-and-down tale of brothers burning with masculine will and passion.
