Zipper Teeth Choir Sequence

Using [zipper reference] and [comic musical mood], show opposing rows rehearsing, then the slider bringing them together in a synchronized final beat. Imagine zipper teeth as a choir that can only sing when aligned. Use original characters and a harmless rehearsal disagreement; avoid turning teeth into a human mouth. Unless a duration is specified, use 12 seconds with three clear four-second beats. Provide reference, camera and continuity notes.

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.
