In a corner of an abandoned laboratory, a group of adorable imp-like ghosts, formed from different colored glowing slime, gathers. They have cartoonish eyes and mouths, composed of translucent slime. These little imps line up, each emitting light of a different frequency, as if preparing for a Halloween choir performance. The laboratory walls are covered with glowing moss, and the background features shimmering flasks and test tubes, creating a lively yet comically eerie atmosphere.
