Dimensional Key in Neon Arcade — Cartoon Adventure

In a bustling retro arcade filled with flickering neon lights, a glossy dimensional key floats above a weathered arcade cabinet. The key's bow contains swirling mini-portals that reveal tiny, shifting dimensions, while the blade emits a soft rainbow trail. The scene is drawn in a bold cartoon style with thick black outlines, saturated neon colors (hot pinks, electric blues, lime greens), and cel-shaded shading. The arcade cabinets display pixel art designs, a checkered floor, and cheerful mascots; ambient CRT glow casts dramatic highlights. The composition is dynamic with a low camera angle, playful yet mysterious, as if the key is about to unlock a new world.
