Bébé joyeux chevauchant un hippocampe géant sous l’eau

Create a dreamy underwater scene with a joyful baby riding a gigantic, elegantly spiraled seahorse. The seahorse has shimmering scales in shades of lavender and gold, with flowing fin-like appendages. The baby wears soft pastel clothing, holding the seahorse’s neck with a delighted, wide smile. The background is a glowing turquoise ocean filled with beams of sunlight, floating bubbles, and sparkling particles. Colorful coral and pink water lilies rest on dark rocks at the bottom. Lighting is ethereal and magical, emphasizing a storybook, fantastical quality. The scene conveys gentle upward movement as the seahorse swims gracefully.
