Requesting Finn and Marceline jamming out in a post-apocalyptic concert scene, while Princess Bubblegum tinkers with glowing tech in the background and BMO records the whole thing like a vintage camcorder. The Candy Kingdom is silhouetted behind them in neon pinks and purples, with floating jellybeans as the audience. Style: vivid, grungy-surreal with a splash of vaporwave.
