A group of Doraemon robots discover an island teeming with oversized insects and peculiar creatures living in perfect harmony. When human interference threatens to destroy this delicate ecosystem, the mechanical cats must work together to protect both the insects and the humans who stumble onto the island. What begins as a simple rescue mission becomes a race against time as the Doraemons navigate through wild grasslands and dangerous bug habitats. The stakes rise when they realize that saving this world means solving a mystery about why these insects exist in the first place. Throughout their adventure, the team relies on their unique gadgets and individual personalities to overcome obstacles that grow increasingly bizarre. The film balances humor with genuine heart, showing how small creatures deserve protection just as much as larger ones. It's part adventure story, part environmental parable, wrapped in the charm and whimsy that defines the Doraemon franchise. The colorful animation brings the insect world to vivid life, making it feel genuinely wondrous rather than creepy or grotesque. Friends separated by size and origin must come together to prove that understanding beats destruction every time.
