At the top of the Cartoon Style image, "Happy Birthday Lucy" in bold neon rock-concert lettering with thick black outline, arched like a stage banner.

Full-bleed vertical cartoon scene with playful, exaggerated proportions, thick outlines, bright saturated colors, and energetic, whimsical poses: On a glitter-splashed stage, a raucous rock band of sprightly old folks performs with a mischievous squad of cats. Center stage, a stylish granny in cat-eye glasses belts into a glittery mic on a cane-shaped stand; beside her, a silver-bearded grandpa shreds a lightning-bolt guitar, using his cane like a slide, foot up on a towering amp. Another senior in a studded leather jacket hammers a keytar. The drummer—an exuberant grandma—pummels a drum kit built from stacked birthday cakes and shiny cymbals, frosting splashing like fireworks. Cats join the chaos: a chonky orange tabby thumps a tiny bass, a slick black cat crowd-surfs on a spinning vinyl record, a Siamese DJ scratches fish-bone-shaped records, and three tiny kittens croon as backup singers into tiny mics. Giant amps resembling scratching posts, tangled cables curling like yarn, rainbow spotlights with paw-print gobos, confetti and balloons shaped like stars and fish bones fill the scene. Low-angle, high-energy composition with motion lines, starbursts, and big expressive faces. Color palette: electric pink, turquoise, lemon yellow, lime green, with deep purple shadows. Keep the vibe funny, loud, and celebratory.

At the bottom, a small cheeky caption: "Still rockin’ after all these meows!" in playful hand-lettered style with thick outline. No other text.
