Magical 2D Transformation Short Video Prompt

Create a 15-second vertical 9:16 magical short video in a real smartphone POV style. Main character: a 7-year-old East Asian girl. Most of the video stays in first-person POV. We often see her small hand holding a black marker, parts of her light blue summer dress, white sandals, and her shadow on the ground. She feels lively, innocent, playful, and real. Visual style: real-world live-action footage mixed with lively 2D cel-animation transformations. Warm summer afternoon light. The world starts realistic, then everyday objects transform into fully animated 2D characters with clear outlines, bright colors, expressive motion, and playful energy. Do not make them partial transformations. The original real object disappears and is fully replaced by the animated version. Magic rule: every time the girl points with the black marker and says “Biu!”, blue hand-drawn sketch lines wrap around the target, ink spreads, and the real object fully transforms into a lively 2D animated version. Scene flow: 1. Rural village path: A real chick transforms into a cute fluffy 2D animated yellow chick, bouncing and flapping. A small farm cart transforms into a playful 2D little dragon creature with four legs, no wheels, blinking eyes, tiny wings, and a wagging tail. 2. High-speed train: From the train window, a real cloud or birds outside transform into lively 2D animated cloud spirits or little birds flying along the moving train. 3. City street: A parked city bike transforms into a lively 2D deer-like creature. A passing bus transforms into a giant orange 2D animated cat. It must keep moving forward along the road like the original bus, stepping ahead with four paws, tail swaying, ears twitching. 4. Ending: Stay in first-person POV. The girl looks down and taps her own dress with the marker, saying “Biu!” Blue sketch lines spread from her dress to her shoes, shadow, ground, grass, trees, and fountain. Her shadow becomes a cute 2D animated little girl shadow spinning happily. The real street gradually turns into a playful 2D animated world. Small 2D animals appear around her: birds, deer, cats, dogs, maybe a tiny dinosaur. Keep the ending bright, joyful, magical, and heartwarming. Important: No duplicate girl. No fake mannequin-like human. No deformed hands. No real object and animated version existing at the same time. No 3D cartoon look. No subtitles, no logos, no watermark. Make the animated characters lively, dynamic, and full of visual charm.
