16-bit pixel art of two steep rocky mountain cliffs facing each other across a deep valley with pine trees, a cute small bear character in a striped shirt standing on the left cliff edge with its paws cupped around its mouth. First second: the bear shouts. Next 2 seconds: concentric pixel-ring sound waves travel across the valley from the bear and hit the right cliff. Final 2 seconds: smaller, fainter rings bounce back toward the bear; the bear tilts its head, listening, and holds still. Crisp pixels, no anti-aliasing, limited 32-color palette, static camera. Sound: one short 'ya-ho' call and its fainter echo, no other speech. No text, no letters, no speech bubbles
