A vibrant, colorful 3D cartoon animation in a vertical 9:16 format, with smooth, bouncy motion, bright playful colors, soft studio lighting, and a cheerful atmosphere for children ages 4-8. Three large magical mystery boxes stand side by side on a clean, colorful background: one bright red, one vivid blue, and one sunny yellow, each with a distinct shape, a glossy finish, and a large ribbon. The boxes suddenly pop into view with sparkling magical particles and bounce gently in place. The red box wiggles first, its lid lifting slightly as a tiny, silly green frog peeks out with wide curious eyes and a cheerful expression. The blue and yellow boxes tremble with anticipation, hinting at more surprises inside. The camera smoothly pushes closer toward the three boxes, keeping them large and clearly visible in the frame. Colorful sparkles drift through the air, creating a sense of playful suspense. Cheerful cartoon sound effects, magical pops, and light upbeat music accompany the animation. A friendly, excited voice says, "One of these boxes has a golden surprise! Can you guess which one?" End with all three boxes bouncing together as the yellow box begins to glow faintly, teasing the mystery. One continuous shot, consistent character and box designs, polished family-friendly 3D animation.
