3D animated video: A cute chibi baby girl (blonde hair, mint-green dress) rides a playful gray donkey on a cloud swing (mountain backdrop, bright sky, fluffy cloud props). The donkey starts with slow, gentle glides—its hooves rest softly on the cloud (making tiny cloud-shaped sparkles drift), and the scene glows brighter with sunlight. It then accelerates into a lively dash (swinging quickly forward through the sky): its body blurs with motion to highlight speed, the soft gray fur shimmers dynamically, and faint cloud-fluff particles scatter in its trail. As it moves, the donkey continuously blows a steady stream of fluffy cloud-shaped bubbles (glowing with sky light) that drift upward, wobbling gently with the breeze, before popping softly (releasing tiny dreamy-themed glitter). The baby girl holds the swing rope steadily, dress fluttering slightly, feet dangling above the cloud, and a bright smile as they dash through the cheerful sky scene. Animation style: soft, whimsical, hyper-dynamic—add motion blur to the donkey/swing and floating bubbles; bubbles sync with the dash rhythm. 12-second clip, 4K, 60fps (ultra-smooth, cloud-swing dash with playful, dreamy interactions).
