Build a dancing Muse: a cute 3D plush mascot with a chubby body, a cream fluffy hood around a round peach face, two small black eyes, rosy cheeks and a tiny smile, short stubby arms and legs, wearing a red hockey jersey with white stripes and black shorts. It dances on its own as soon as the page opens: a real choreographed loop with bounces, arm waves, a spin, a hip sway and a big finish pose, under colorful stage lights with confetti. The fur should look soft and the moves should feel bouncy and alive, with squash and stretch. One self-contained HTML file, no external assets, and it should fill any window. It should feel joyful the moment it loads.
