3D animated video: A cute chibi baby (curly blonde hair, orange-white heart outfit) rides a playful seahorse in an underwater-themed play area (colorful dotted cups, seaweed decor, bright aquatic backdrop). The seahorse starts with slow, gentle glides—its body drifts softly over the sand (making tiny star-shaped sparkles drift), and the scene glows warmer with underwater light. It then accelerates into a lively dash (swimming quickly forward through the area): its body blurs with motion to highlight speed, the striped orange-yellow surface shimmers dynamically, and faint cup-particle trails scatter in its wake. As it moves, the seahorse continuously blows a steady stream of glossy star-shaped bubbles (matching the cup props) that drift upward, wobbling gently with the water flow, before popping softly (releasing tiny playful-themed glitter). The baby holds the seahorse’s head steadily, outfit fluttering slightly, feet dangling above the sand, and a bright smile as they dash through the cheerful underwater play scene. Animation style: vibrant, whimsical, hyper-dynamic—add motion blur to the seahorse and floating bubbles; bubbles sync with the dash rhythm. 12-second clip, 4K, 60fps (ultra-smooth, underwater-play dash with playful, colorful interactions).
