The Upgrade Bench is a medium-sized, interactive station with a cartoonish and vibrant design, featuring a bright blue and yellow color scheme with glowing accents. It has a sturdy, angular metal frame with smooth, polished surfaces, and a large, circular interface screen displaying upgrade options in bold, colorful icons. The bench includes small, decorative gears and bolts embossed on its sides, adding to its mechanical theme, and emits a soft, pulsating glow to indicate its functionality.
