The Season 90 Boost is a vibrant, cartoonish 3D model featuring a dynamic, flowing energy trail with a gradient color scheme transitioning from electric blue to neon pink. The boost emits a soft glow and has a smooth, polished surface with subtle particle effects that sparkle as it's activated. The shape is sleek and aerodynamic, with a slightly curved form that tapers at the ends, designed to visually enhance the speed and agility of the vehicle in Rocket League.
