Create a 30-second continuation in 16:9 with synchronized cinematic sound. Dori is a small 2.5D petroglyph whale with a rough charcoal one-line body, tiny flippers, split tail, and one cobalt-blue eye. Preserve his silhouette and proportions. Continue as the car-window reflection becomes Ulsan harbor at blue hour. Use premium stylized 3D animation, blue-gold lighting, tactile water and mist, subtle squash-and-stretch, and restrained emotion. 0–3s: Dori floats above calm water. He notices pairs everywhere: two birds, two tugboats, paired crane lights, two waves. He looks at the empty space beside himself. His blue eye dims. 3–10s: The five-note motif emerges from harbor sounds. Dori sees golden lights, blue reflections, and mist. His eye brightens. Using his tail like a pencil, he lifts reflected light from the water and draws a giant whale outline beside himself. 10–18s: The outline becomes a whale made of mist, reflections, and golden-blue light. Dori circles it happily and gives a tiny greeting chirp. Moving reflections make the whale appear to follow him, and Dori believes he has made a friend. 18–24s: They move side by side. Dori turns; the light whale seems to turn. He spins; it forms a larger graceful curve. Dori gently leans against its glowing nose. Hold a warm quiet beat. 24–30s: A departing ship creates a gust and wave. Mist shifts and the whale breaks into glowing lines. Dori tries to hold them, but they pass through him and vanish. He settles on a buoy, eye dim, no tears. At 29s, a tiny cobalt line floats in and touches his nose. Dori looks up. End on the glowing line leading toward a dark green bamboo forest. Camera: calm movement, wide lonely opening, intimate creation shots, slow pullback during the loss. Audio: harbor ambience, water, chimes, greeting chirp, five-note motif, near silence, then a pencil-like sound. No dialogue, text, logos, tears, destruction, melodrama, or copied characters.
