Donut Cat Snorkel Video Prompt

Create a 15-second 16:9 video on a pure white background with a locked front camera and centered framing. No camera movement, cuts, transitions, text, captions, or extra elements. Feature a photorealistic golden powdered-sugar donut with a simple black 2D hand-drawn chubby cat wearing a snorkel, mask and flippers. Keep the donut realistic and the cat/waves as minimal black line-art. Never make the cat 3D. 0–2s: The donut stays still while the happy cat floats inside it, gently paddling and kicking. Small black wave lines animate around the donut. 2–3s: The cat paddles faster, notices the donut, looks hungry, licks its lips and gives a mischievous smile. 3–6.5s: The cat bites the donut repeatedly. Show clear progressive eating: whole donut → big bite → half donut → tiny piece. Add small crumbs and funny chewing expressions. Every missing section must disappear through a visible bite - never dissolve or vanish. 6.5–7.5s: The cat eats the last piece. The donut is completely gone. It looks around, realizing it ate everything. 7.5–8.5s: The cat becomes adorably sad, with lowered ears, drooping paws and a pout, staring at the empty space. 8.5–10s: A fresh complete powdered-sugar donut drops from above and lands perfectly around the cat. The cat instantly becomes excited and the wave lines return. 10–11.5s: The cat hugs the new donut with closed eyes and a huge happy smile. 11.5–13s: It happily wiggles its paws and flippers, floating in the donut. 13–14s: The cat looks at the camera and gives a cute little wink. 14–15s: A tiny bubble pops from the snorkel. The cat kicks its flippers twice and smiles brightly as it floats happily inside the untouched donut. Keep the same visual continuity from beginning to end: realistic donut + black hand-drawn cat, snorkel, flippers and waves only.
