Doraemon: Nobita and the Animal Planet is a 1990 anime movie, the 10th movie in the Doraemon Film Series based on Doraemon's Long Tales.
This time, Doraemon and friends are the guests of a World of Funny Animals after stepping into a portal made of gas which inexplicably forms in Nobita's house. Befriending a local dog boy named Chippo, Doraemon and friends eventually learns of an ancient legend from the animal folks - the tales of the Nimuge, a race of demons from outer space who used to terrorize the animals' ancestors. But then the Nimuge returns, and it's up to the gang to save the animal world at all costs and learn some important Green Aesops along the way.
Doraemon: Nobita and the Animal Planet contains examples of:
- Adaptational Badass: In the manga, Doraemon has basically no answer to the Nimuge commander burning down the forest, and the heroes are only saved by the arrival of The Cavalry. In the movie, Doraemon finds his raincloud-making machine and puts out the fire before The Cavalry arrives.
- Adaptational Wimp: In the film, Shizuka accompanies the others during the final battle but isn't seen doing any fighting, her main contribution being to light the fireworks that lure the Nimuge into their ambush. In the manga, she wields an Air Cannon and helps shoot down the invaders alongside everyone else.
- After the End: Pretty much the state of planet Nimuge, a wasteland barely recovering after over-development and rapid terraforming.
- Alien Invasion: Inverted. The aliens are actually a hostile race of humans trying to annihilate a planet occupied by anthropomorphic animals.
- All Myths Are True: The denizens of the animal planet believe in the Legend of the Nimuge from before their race's creation, where their ancestors were enslaved by the Nimuge until their exodus, fleeing to a new, uninhabited planet to evolve and develop and leaving the Nimuge on the neighbouring, rotting world. Turns out the Nimuge are humans, who after over-developing and terraforming, destroyed most of the local flora and fauna and turning their world into a harsh wasteland. A good human scientist then devised a plan to transport most of the animals to this current world, where they then grew and evolved into their current state.
- By-the-Book Cop: Chippo's father is the local animal policeman dedicated to his job, though since the crime rate in the animal world is ridiculously low he doesn't get much to do. One of his scenes have him breaking up a fight between a goat-man and a pelican postman because the goat accidentally ate a letter meant for him without being informed by the pelican...
- The Cavalry: The Galactic police show up in the end to reinforce the heroes and arrest the invading Nimuge.
- Clothes Make the Superman: A headscarf example, the animal headscarf gadgets given by Doraemon bestows its wearer the traits from their respective animals. Shizuka who gets bunny ears gains the sharp hearing of rabbits, Suneo who has a fox suit has the keen sense of smell associated with foxes, while Gian who has a gorilla outfit gains the strength of one.
- Cool Starship: The legendary Star-Shaped Craft, which the animal-people's ancestors mistakes it to be "a magic star which carries God". It turns out to be a star-shaped golden spaceship used by the good scientist to guide the animal-people's ancestors away from the Nimuge world.
- The Dreaded: The Nimuge, horrifying demons who terrorized the animal beings' ancestors in ancient times, until the animal exodus. Even in the present, Chippo's father would scare him into behaving with taunts like "The Nimuge will devour naughty children!"
- Dressing as the Enemy: Nobita managed to infiltrate a Nimuge cell by donning the protective suit all their member wears. It helps that thanks to the "Lunar Luck" cake still in effect, the Nimuge actually slipped and knocked himself unconscious while trying to detain Nobita.
- Erudite Orangutan: The animals are led by Mayor Utan, a wise and noble orangutan who cares dearly for his people. He spends the entire night before the war praying for safety of the other animals and to seek guidance in the upcoming battle against the Nimuge.
- Flying Saucer: The Nimuge invasion fleet consists of saucer-shaped crafts.
- Gaia's Vengeance: Invoked on purpose in the final battle when Doraemon uses a gadget that give lives to trees and plants, making the forest vegetation come to life and attack the Nimuge - including dropping heavy fruits knocking out several Nimuge soldiers, releasing powerful pollen powder that seeps through their helmets making them sneeze uncontrollably, using roots and vines to restrain the Nimuge. It works until the Nimuge leader brings out a tank equipped with what seems to be a dozen flamethrowers.
- Good Luck Charm: Doraemon's "Lunar Luck" moon cake, which bestows an hour and forty-five minutes' worth of fortune to anyone who eats it. It works best on people whom are Born Unlucky, so naturally when Nobita consumes the cake it works miracles.
- Green Aesop: Hey, it's from 1990. The entire story runs on this; the animal-people were descendants from ordinary animals evacuated to another planet after their original home was destroyed by excessive development from the native human population. Left on their own, these animals evolved to a human-like state and lives in their own beautiful utopia, while their original planet, whose human inhabitants are referred to as "Nimuge" by the animal folks spends their entire lives scavenging wastelands. When the Nimuge invades, the animal world quickly turns into a horrifying hell-hole like the Nimuge's world. Even back home in Tokyo, Nobita's mother Tamako is actively campaigning in a petition to stop the development of the piece of land behind the school into becoming a golf resort.
- I Have Your Wife: After the Nimuge's initial invasion, they announced they've captured a hostage, a little puppy girl which turns out to be Chippo's cousin, Romi. Prompting Nobita to go on a solo rescue mission when he uncovers the Star-Shaped craft later.
- Hazmat Suit: All members of the Nimuge race wear these by default due to the severely polluted state of their homeworld, leading to the animal folks believing them to be monsters and hiding the fact that the Nimuge are actually humans.
- Hero of Another Story: The unnamed police spy who had infiltrated the Nimuge's ranks is a capable secret agent of his own, but he's pretty much there to serve as a quick distraction for Nobita to rescue Romi and escape from the Nimuge world. After the final battle, one of the heroic soldiers backing up the animals remove his goggles to flash a smile at Nobita, where it turns out that's the spy who had survived and escaped the Nimuge on his own after all.
- Human All Along: The Nimuge demons feared by the living animal folk are humans.
- Humans Are the Real Monsters: Yeah, those scary Nimuge demons from the legends? They're the humans of the neighbouring planet who destroyed their world, leading to the animal exodus several millennia ago. And they've learnt NOTHING from their past, ready to invade the now-peaceful animal planet to "reclaim what rightfully belonged to the humans".
- Landfill Beyond the Stars: The Nimuge's world consists mostly of trash and waste, thanks to having squandered their planet's resources in ancient times which they never recovered from. The surface is also highly toxic with acid rain falling from the skies, with the Nimuge wearing protective suits all the time.
- Lost in Transmission: Chippo attempts calling Doraemon and friends - now safely back on Earth - for help when the Nimuge aliens invade using the transceiver from Doraemon's Expedition Set, but the line goes dead mid-transmission. Doraemon, Nobita, and the rest of the gang then decides to return to the Animal Planet, this time using Doraemon's shuttle.
- Nice Job Breaking It, Hero: The Nimuge are basically confined to the Moon near the Animal Planet until Gian and Suneo - who inquisitively followed Doraemon, Nobita and Shizuka through the Teleportation Gas - accidentally messed with the gas' generator, opening a portal leading to the Nimuge world allowing them to enter the Animal Planet. They promptly launch an invasion a day after Doraemon and gang took their leave.
- No Cartoon Fish: Averted, it's a race of cartoon fish dressed in suits and having a karaoke party which rescued the drowned Suneo.
- Or Was It a Dream?: Nobita believes his encounter with the world full of sentient animals is just a dream. But then he sees a flower he recovered from his dreams in a vase on the television, which his mother said she picked up on the floor outside his room.
- Rock Beats Laser: Zig-zagged. It was initially played straight when the Nimuge's invasion fleet consisting of flying saucers and armed soldiers gets beaten and shot down by the poorly-armed animal militia and Doraemon and gang who have minimal equipment. But then the Nimuge Commander brings out a tank bristling with weaponry, and it all goes to hell for the heroes.
- Running Gag: Two of them:
- Gian being mistaken by a gorilla sailor as his son, trying to spank him for "slacking"... and realize he had knocked out Gian by accident.
- The animal-people mistakenly calling Doraemon a tanuki, a known Berserk Button for Doraemon. And Doraemon protesting ("How many times do I have to repeat this? I'm NOT a tanuki!") only to unintentionally offend a real tanuki resident.
- Sleepwalking: How Nobita managed to find the animal planet in the first place, by sleepwalking through a portal that opened outside his toilet. He woke up from his sleepwalk the first time, sees Chippo and his animal friends, and quickly leaves before falling asleep in the corridor outside, dismissing everything to be just a weird dream. And then he ends up sleepwalking into the same place again the following night...
- Tank Goodness: After losing communication with his ground assault team, the Nimuge leader decide to bring out his trump card, a massive battle tank loaded with cannons, flamethrowers, and enough weaponry to incinerate the entire forest as a last-ditch attempt to wipe out the animals.
- Those Were Only Their Scouts: Subverted. After defeating the first wave of Nimuge invaders, the animals end up being attacked by the Nimuge Commander's tank, which incinerates most of the forest and soundly turns the battle in the Nimuge's favour just as a horde of flying saucer reinforcements arrive. But then, to everyone's surprise, the new wave of saucers starts dousing the forest fire instead, just as a different group of human soldiers start descending to reinforce the animals and disable the tank. It turns out the second wave of saucers are human allies from the Galactic police force.
- World of Funny Animals: The population of the animal planet. They're an example of the trope with a scientific explanation behind their existence, however, as their ancestors - ordinary animals - were evacuated from a war-torn wasteland planet centuries ago and deposited into an empty planet, where the animal population then evolves on their own after generations.
