Create a short animated video of Mochi. Use the provided start frame strictly as the character reference. Mochi is a cute, soft, round, mochi-like character, pure white color, smooth surface, minimalist design. FACE (DO NOT CHANGE): Two large black oval eyes, small centered dot mouth, no nose, no eyebrows. Face must stay identical to the start frame. ANIMATION: Simple, slow, readable motion. One action only. Body squash and stretch allowed. Face remains static. ACTION: Mochi notices nothing happening, pauses happily, stays still briefly, freezes, then returns to neutral. LOOP: The animation must end in the exact same pose as the beginning. Seamless loop, no ending gesture, no fade out. CAMERA: Static, centered, no movement. STYLE: Clean, cute, non-cinematic. AUDIO: Soft loopable background music, no vocals. DURATION: 8 seconds. NEGATIVE: realistic, cinematic, changing face, camera movement, fast motion, text, logo, watermark
