Create an illustration of a [OBJECT] in a retro cartoon style. Use only flat, solid colors with no gradients, smudging, airbrushing, or blur. All shading and highlights should be made from clean, separate color blocks. Outline all shapes with thick, bold black lines. Use a simplified color palette (such as teal, coral, mustard, and white) for a vintage feel. Add small sparkle accents or motion lines for charm, but keep the icon the clear focus. Set the illustration on a plain white background. The final result must be crisp, clean, and vector friendly with sharp edges and no texture or raster effects. Square aspect ratio.
