Doraemon's Long Tales (Doraemon's Long Tales #10)

One night, Noby walks through a strange mist that leads him to Storybook Planet, a nature-friendly world where animals live in peace and harmony. Noby and the gang are impressed by how well the animals seem to be running their planet. They befriend a young dog named Chippy and return to Earth, only to receive news from Chippy a few days later that Storybook Planet has been attacked by Infernoids, evil monsters that appear in myths. With a wilting flower taken back from the animals' planet as their only clue, Noby and his crew climb aboard the Space Lifeboat to save their animal friends. Can they make it in time? Who are the Infernoids, and what do they want?

Environmentally-themed, the tenth tale of the Doraemon's Long Tales series!
