Seedance 2.0 Video Prompt: Obsidian Dragon Ambushing Hamster

the prompt

Obsidian dragon hiding in sleeve → ambushing hamster

A girl's arm in loose sweater sleeve extends into frame, sleeve opening slightly, a small obsidian-black shiny mini dragon (ruby-red eyes, sharp tiny horns) emerges from the sleeve, background is a desk with a small cage, 
0-4s: dragon slowly crawls out onto the arm, claws lightly gripping fabric leaving fine marks; 

4-9s: dragon silently approaches the golden hamster running in its wheel on the desk, suddenly opens mouth with a faint low growl + exhales thin black smoke tendril, hamster panics and runs wildly crashing into cage wall; 

9-15s: girl's other hand reaches in, index finger gently taps dragon's head to stop it, dragon obediently shrinks back into sleeve leaving only tail wagging, 

camera from sleeve opening close-up quick tracking push to full desk scene then subtle orbit, overcast cool natural light + faint desk lamp fill, realistic fur-scale interaction, detailed skin texture, cinematic depth of field, natural physics collisions
