At the top of the Cartoon Style image, “Happy birthday Sam ❤️” in massive spiky heavy‑metal chrome letters with a neon purple glow, arched like a concert banner.

A playful, high-energy Cartoon Style scene inside a gothic sci‑fi gym on a starship: chibi Warhammer-style space marines in oversized glossy black power armor with neon magenta, cyan, and acid-green accents, thick outlines, exaggerated proportions, and goofy heroic poses. Center marine bench‑presses a barbell made from an electric guitar neck with skull/planet weight plates; tongue out, comedic sweat droplets, confetti shaped like lightning bolts and stars flying. On the left, a marine curls meteor dumbbells while headbanging; a floating servo‑skull boombox with headphones blasts music. On the right, a marine swings a planet-shaped kettlebell while screaming into a microphone, next to a glowing amp stack and drum kit with stylized skull motifs (no readable text). A birthday cake sits on a weight bench with sparkler candles; balloons shaped like moons and tiny guitars; hazard‑stripe mats; gothic arches and chains in the background. Dramatic concert lighting beams, neon rim lights, bright saturated colors, chunky inked outlines, shiny highlights on the black armor, whimsical, energetic poses and silly expressions. No logos or additional readable text.

At the bottom, add a small cheeky caption on a jagged ribbon: “May your gains be grim and your metal heavy!”
