At the top of the Cartoon Style image, "Happy 18th Birthday Sam" in big, bouncy bubble letters with thick black outlines and splashy ocean-blue highlights, arched like a wave.

A bright, funny cartoon beach scene: a jubilant 18-year-old teenage boy with exaggerated proportions (big head, huge grin, expressive eyes, oversized hands/feet), bareheaded (no hat), wearing colorful swim shorts and a short-sleeve rash guard, belly-sliding down a slick muddy slope straight into the turquoise sea. He kicks up sweeping arcs of muddy water, leaving a playful skid trail behind him. Ahead, giant lively waves curl high with frothy white foam swirls and sparkling droplets in saturated blues and teals. Comedic touches: a startled crab hopping aside, a cheeky seagull mid-flap, a starfish clinging to one foot, and a bit of seaweed stuck like a goofy mustache. Sun-bright sky with chunky clouds, golden sand, and glossy wet mud textures. Thick outlines, bold saturated colors, clean cel shading, energetic motion lines, and bouncy, whimsical shapes. Vertical composition with a dynamic diagonal from mud slope to surf, the boy centered in an energetic pose. No extra text or onomatopoeia elsewhere in the scene.
