Character sticker design of 'Mochi', a chubby round pastel-mint axolotl mascot. Consistent character bible: soft mint-green body, coral-pink feathery external gills, big glossy black eyes with two white catch-lights, tiny rosy cheek blush, four stubby limbs, permanent gentle smile. Flat 2D kawaii vector-illustration style, bold clean 6px cream outline, cel shading with one soft ambient-occlusion shadow, thick white sticker die-cut border. Centered, full body, front three-quarter view, on a flat solid lavender background. Ultra clean, crisp edges, print-ready. No text, no watermark.
