At the top of the Cartoon Style image, write "Happy birthday " in big, bouncy bubble letters with thick black outlines and rainbow-confetti fill.

Full-bleed, playful cartoon scene: a beaming runner with exaggerated long legs and huge, squeaky sneakers sprints along a racetrack shaped like a giant 50, dynamic tilt angle, squash-and-stretch motion lines. Behind them, an anthropomorphic “50” (chunky digits with tiny sneakers and a sweatband) huffs and puffs trying to keep up, adding comedy. The runner clutches a cupcake baton, wears a party hat and headband, with sparkling sweat drops and streamers trailing like a cape. Finish-line ribbon across the “0” shows the single caption: “Outrunning 50!” Balloons, candles, and confetti burst around a simple stadium backdrop so the characters pop. Thick outlines, bright saturated colors (electric blue, lemon yellow, hot pink, lime green), whimsical, energetic poses, clean cel shading, crisp lighting, bold cartoon vibe.
