Deep

In a post-apocalyptic future, humanity has abandoned Earth due to an ecological catastrophe that flooded the planet and devastated sea life. However, a group of creatures, including the gigantic Kraken squid, have formed a colony in the deep ocean, where its grandson, Deep, lives with friends Evo the anglerfish and Alice the shrimp. As Deep searches for his hero, Nathan the white whale, they encounter various obstacles and allies, including a friendly Moray eel named Maura, who joins their quest to stop the villainous Emperor Penguin commander Darcy from freezing them on the Ark-3 spaceship. Along the way, they overcome challenges and ultimately triumph over Darcy's plan, securing their freedom and starting a new future for themselves and the other sea creatures.
