The Season 39 Boost is a vibrant, cartoonish 3D model featuring a sleek, aerodynamic design with smooth, polished surfaces. It emits a dynamic, glowing trail in a gradient of neon colors, transitioning from electric blue to hot pink, with subtle particle effects for added visual flair. The boost nozzle is angular and symmetrical, with intricate engraved patterns that reflect the season's theme, adding a touch of ornate detail to the otherwise streamlined form.
