3D animated video: A cute chibi baby (blue bob hair, red-blue outfit) rides a playful white duck on a Lego-themed track (colorful block rails, toy structures, bright sunny sky). The duck starts with slow, gentle steps—its webbed feet tap softly on the blocks (making tiny Lego-shaped sparkles drift), and the track glows brighter with cheerful light. It then accelerates into a lively dash (scurrying quickly forward along the block track): its body blurs with motion to highlight speed, the smooth white feathers shimmer dynamically, and faint block-colored particles scatter in its trail. As it moves, the duck continuously blows a steady stream of colorful Lego-shaped bubbles (glowing with track light) that drift upward, wobbling gently with the breeze, before popping softly (releasing tiny playful-themed glitter). The baby holds the duck’s head steadily, outfit fluttering slightly, feet dangling above the track, and a bright smile as they dash through the cheerful Lego track. Animation style: vibrant, whimsical, hyper-dynamic—add motion blur to the duck and floating bubbles; bubbles sync with the dash rhythm. 12-second clip, 4K, 60fps (ultra-smooth, Lego-track dash with playful, colorful interactions).
