Cartoon Leprechaun in a Cozy Underground Bunker

Cartoon-style illustration of a cheerful leprechaun inside a dim underground bunker. He wears a bright green suit with a buckled hat, red beard, and oversized shoes. The bunker has concrete walls, hanging pipes, crates, sandbags, and blinking green and amber lights. A wooden table holds a sparkling pot of gold coins. The scene uses bold black outlines, flat saturated colors, and playful lighting with a warm yellow-green glow. Add whimsy and a lighthearted, humorous vibe, with exaggerated expressions and dynamic composition.
