3D animated video: A cute chibi baby girl (pink hair, yellow overalls) rides a playful spotted cow in a flower-filled circular meadow (colorful rainbow edge, bright sunlight, lush green backdrop). The cow starts with slow, gentle steps—its hooves tap softly on the grass (making tiny flower-shaped sparkles drift), and the scene glows warmer with outdoor light. It then accelerates into a lively dash (trotting quickly forward around the meadow): its body blurs with motion to highlight speed, the soft black-white fur shimmers dynamically, and faint flower-petal particles scatter in its wake. As it moves, the cow continuously blows a steady stream of vibrant flower-shaped bubbles (matching the meadow’s blooms) that drift upward, wobbling gently with the breeze, before popping softly (releasing tiny cheerful-themed glitter). The baby girl holds the cow’s horns steadily, overalls fluttering slightly, feet dangling above the grass, and a bright smile as they dash through the cheerful floral meadow scene. Animation style: vibrant, whimsical, hyper-dynamic—add motion blur to the cow and floating bubbles; bubbles sync with the dash rhythm. 12-second clip, 4K, 60fps (ultra-smooth, floral-meadow dash with playful, colorful interactions).
