Pixar Style Boy and Dolphin Underwater

"A chubby little boy dancing underwater with a playful dolphin. The boy has big expressive eyes, soft chubby cheeks, and wears a colorful diving outfit with cartoon-like details. He looks joyful and surprised, spinning with his arms open. The dolphin swims around him playfully. The water is crystal-clear with dreamy rays of sunlight filtering through, bubbles everywhere, and soft underwater plants swaying. Pixar-style 3D animation, highly detailed fur/skin textures, cinematic lighting, soft pastel colors, cute proportions, magical and heartwarming vibe."
