Dimensional Key in Neon Arcade

Cartoon-style neon arcade scene featuring a magical dimensional key floating above a checkered floor. The oversized key is gleaming silver with a circular head etched by glowing runes, and a shaft pulsing with tiny notch marks. From the key's tip erupts a swirling dimensional portal—ribbons of magenta, electric blue, and gold—creating mini-space distortions with sparkles and tiny stars. The background shows retro arcade cabinets with bright CRT screens, pixel-art sprites, and a glowing neon 'Arcade' sign. Bold black outlines, rounded shapes, and glossy highlights give a playful, whimsical vibe. The camera is a low-angle view, making the key loom large as if about to unlock another dimension.
