A magical underwater-themed t-shirt design featuring adorable cats swimming in the deep sea. Multiple cats are illustrated in a hand-drawn, cartoon style with navy blue and teal ink on a white background. The cats are wearing diving masks or swimming with tiny fins, floating among jellyfish, seahorses, and coral formations. Some cats are curled up resting on seaweed, others are playfully chasing fish bubbles. The design includes various ocean elements like starfish, shells, floating bubbles of different sizes, and gentle water currents. The cats are arranged in a scattered, organic composition across the design area, creating a serene, underwater feeling. The illustration style is clean and modern with bold outlines, solid fills, and charming details like whiskers and paw pads visible through the diving masks. | PODspy AI Design
