Gatinho branco em pixel art boiando em uma piscina ensolarada

create a pixel art image of a cute, big, fluffy white cat floating on a pool floaty, wearing yellow boxer shorts and yellow sunglasses, holding a bitten watermelon slice. Use a limited 16-bit color palette with bright blue pool water, warm sunny skies, and dithering for shading. Emphasize crisp, clean pixels, minimal anti-aliasing, and retro-style details for a nostalgic summer vibe. Keep the composition vibrant and playful.
