Pop-up Book Paper Dragon Animation

Pop-up book paper craft animation, 15 seconds, 16:9. Layered cut-paper 3D pop-up book style, visible paper folds and tabs, soft warm storybook lighting, hand-crafted texture, shallow depth of field on an open book. No voice, audio: gentle music box, page-turning sounds, a low rumble building to a roar. ACT 1 (0-4s): An open storybook on a wooden table. The first paper page rises to reveal a layered cut-paper mountain landscape at dusk, tiny folded pine trees standing up. Slow push-in toward a dark cave opening in the paper mountain. ACT 2 (4-8s): Hard cut. A page turns and pops up a cave interior - layers of paper stalactites unfold, and a pile of folded golden paper treasure rises into place, glittering. Camera drifts deeper into the cave. ACT 3 (8-12s): Hard cut. Among the paper treasure, a massive folded paper dragon slowly unfolds and rises - wings spreading in layered paper sheets, neck extending upward, filling the frame. The rumble grows. ACT 4 (12-15s): Hard cut. Close-up as the paper dragon's eye snaps open, glowing amber, and it lets out a roar - paper flames unfold from its jaws toward the camera. Freeze on the dragon filling the whole open book. Final roar.
