A Very Strange Walk

Prompt:  Cinematic, ultra-realistic, photorealistic, 5-second video. A young woman is walking her cheerful golden retriever along a quiet city sidewalk just after a heavy rain. The street is wet, with several large puddles reflecting the cloudy sky. The camera smoothly tracks them as they approach the biggest puddle. Suddenly, an enormous dolphin explosively leaps out of the puddle in a massive splash, as if the tiny puddle were connected to the open ocean. The woman instantly freezes with wide eyes and an open mouth in complete disbelief. The dog jumps backward, barks once in surprise, then tilts its head in confusion. The dolphin performs one elegant mid-air flip, briefly appears wearing oversized sunglasses, gives a playful wink, then dives straight back into the tiny puddle and completely disappears. Only gentle ripples remain. The woman and the dog cautiously step closer, lean over the puddle, and stare into it in stunned silence. Comedic timing, expressive reactions, realistic water physics, cinematic lighting, shallow depth of field, smooth camera movement, highly detailed, 4K, HDR, natural colors.
