Echo Returns With a Tiny Painting

Create a 12-second silent original cartoon from [hiker and cave references]. The hiker calls toward the cave; a tiny echo character emerges holding one modest landscape painting of the same mountain, proudly presents it and waits. Preserve painting orientation and cave geometry. Use three restrained reaction beats, no readable text and no borrowed character designs.

Confirm required reference images and timing inputs are present before generating. Keep objects, identities, spatial relationships and light direction consistent. Render the clip when video generation is supported; otherwise supply a timed shot list, reference checklist and generation-ready prompt, labeled as a production plan. Do not claim rendered output without an actual file. Check the opening, transition and final frame against the stated counts and geometry.
