偷吃包子，螃蟹背锅

25-second, 16:9 cinematic 3D Pixar-style animation, ultra-detailed, warm golden-hour sunlight, shallow depth of field, tropical island beach hut setting with a thatched roof, bamboo railings, turquoise sea and green rock islands in the background, wooden table.

CHARACTER LOCK: Yuuva – chubby toddler girl, huge dark brown eyes, rosy round cheeks, messy dark brown hair in a tiny top bun with a small white flower clip, cream leaf-trim sleeveless dress, small shell necklace.
GRANDMA – elderly island woman, silver-grey hair in a bun, deep expressive wrinkles, big dark eyes, cream embroidered blouse, wooden bead bracelets, strict but loving.
CRABBY – small bright orange cartoon crab with huge white googly eyes, big claws, expressive eyebrows.
PROP: steamer basket with white fluffy steamed buns (baozi), wooden spoon, small plate.
Same faces, outfits and style in every shot.

0–2s: Extreme close-up. Yuuva stuffs a white bun into her mouth, cheeks full, eyes darting sideways. Grandma sits blurred beside her, back half-turned. Bun basket in the foreground.

2–4s: Medium shot. Grandma turns and looks suspiciously at the basket. Yuuva, mouth full, innocently points her little finger off-screen at the crab. Crabby appears at the table edge.
Yuuva (muffled, innocent): "Crabby!"

4–6s: Close-up. Crabby freezes, huge eyes wide with shock, claws raised slightly, looking worried and confused.

6–8s: Two-shot. Grandma squints sternly at Crabby, then at Yuuva, then back. Yuuva pretends to be innocent, puffing her cheeks. Grandma closes her eyes, takes a slow breath, and sighs.
Grandma (stern): "Hmm… Crabby."

8–10s: Crabby on the table, looking angry and offended with furrowed eyebrows, claws out to the sides, shaking his head. Then a bun on a wooden spoon is held in front of him as Grandma gives him a "punishment".

10–12s: Close-up of Yuuva looking at the camera with a sneaky, shy smile, eyes sparkling. She grins and slightly raises her eyebrows.

12–14s: Close-up of Grandma, frowning intensely with her bun on the spoon. Side angle: she lowers the spoon to a plate in front of the sea.

14–16s: Low angle on the table. Yuuva rubs her little hands together, eyeing the bun with a greedy look. Crabby is at the side, defeated.

16–18s: Close-up. Yuuva sneakily bites the bun again while Crabby, beside her, holds the bun with his claws in a panic, eyes glancing sideways.

18–21s: Wide shot. Grandma sits with arms crossed, eyes closed, chin up, still grumpy. Yuuva and Crabby sit quietly beside her. Yuuva looks at Grandma, raises a finger as if making a point, then slowly offers her a bun with a sweet smile. Grandma peeks with one eye, melts, and smiles warmly.
Yuuva (sweetly): "Sorry, Grandma…"

21–23s: Extreme close-up. Yuuva leans in and hugs Grandma's cheek, sticking out her tongue playfully at the camera with a cheeky look. Grandma's grey hair in the foreground.

23–25s: Final shot. Crabby alone on the table, claws raised high, angry-eyed, furious about being blamed. Hold on his grumpy face. End.

AUDIO: gentle ukulele island music, soft ocean waves, seagull sounds, bun-biting and munching sounds, small claw clicks, baby giggles, Grandma's sigh.

Create a 25-second polished 3D animated comedy, 16:9. A tropical beach hut overlooks a turquoise sea and green islands; warm afternoon light and shallow-focus close-ups. Keep the same toddler with rosy cheeks, dark top bun and white flower clip, cream leaf-trim dress and shell necklace; the same silver-haired grandmother in a cream blouse; and one small orange crab with large eyes and expressive claws. The wooden table holds {{snack}} in a bamboo basket, a spoon and a plate.
0-4s: Close-up: the toddler secretly eats a snack, cheeks full, while Grandma turns from the basket. The toddler points at the crab and says, muffled, "Crabby!"
4-8s: The crab freezes, eyes wide and claws lifted. Grandma looks from crab to toddler, sighs and says, "Hmm... Crabby."
8-12s: The offended crab shakes its head while Grandma presents a snack on the spoon. Cut to the toddler's sly smile and Grandma lowering the spoon to the plate.
12-18s: The toddler rubs her hands together, sneaks another bite while the crab tries to hold the snack, and looks guiltily toward Grandma.
18-23s: Wide shot: Grandma folds her arms. The toddler offers her a snack and says, "Sorry, Grandma..." Grandma peeks, softens and smiles; the toddler hugs her cheek and playfully sticks out her tongue.
23-25s: Hold on the crab alone, furious about taking the blame, claws raised. Maintain character shapes, outfits and table geography. Audio: gentle ukulele, waves, gulls, munching, claw clicks, giggles and a sigh; clear synchronized voices. No titles or logos.
