Use the uploaded padded three moon jellyfish as the exact locked identity, count, size hierarchy, bell shapes, tentacle layout, formation and translucent premium painted 2.5D material reference. On a mathematically pure black #000000 matte with a completely fixed camera, create one uninterrupted five-second self-contained protective contraction while all three complete bells and every attached tendril remain centered inside the central 70 percent. The entire frame contains exactly these three jellyfish from the first frame to the last frame. The upper third and every area outside the three jellyfish remain perfectly empty pure black in every frame. Begin with 0.7 seconds of alive asynchronous calm contractions. The largest bell then contracts firmly first, followed by the two smaller bells at distinct delayed phases; the formation closes inward by less than four percent and lowers locally by less than five percent of frame height. No external cause, visitor, silhouette, shadow or object is shown or implied. During the final second the same three jellyfish reopen to their exact original spacing, height, brightness and asynchronous calm cadence. Preserve every bell and tendril throughout. NEGATIVE PROMPT: No fourth object, no other animal, no ray, manta, shark, dolphin, predator, visitor, silhouette, shadow, tail, fin or body entering from any edge; no object in the upper third; no scenery, water band, gradient, rectangular aura, external light, spotlight, particles, camera movement, zoom, cut, group traversal, frame exit, synchronized mechanical pumping, static-card slide, extra or missing jellyfish, merged bells, fused, missing, broken or detached tendrils, opaque bodies, darkness through bodies, hard neon outline, fade, opacity loss, disappearing body, ghost, crossfade, teleport, duplicate, morphing, blur, freeze, text, logo, UI or reels.
