At the top of the Cartoon Style image, “Happy 18th Birthday Sam” in bold, bubbly surf-splash lettering, white with aqua outline, arcing across the sky.

Funny, playful cartoon scene with exaggerated proportions and thick black outlines: a joyful older teenage boy (around 18), bareheaded with messy wet hair (no hat), grinning wide, sliding belly-first down a muddy dune like a slip-n-slide straight into the turquoise sea. Mud streaks and globs fly in comic arcs, splatting into sparkling foam as huge, friendly, curling waves rise behind him. He wears colorful swim trunks, limbs flailing in an energetic, whimsical pose; big splash where mud meets water, with dynamic motion lines and droplets. Add goofy details like a startled crab hopping aside and a seagull lifting off, both with expressive cartoon faces. Bright saturated palette—deep blues and seafoam greens for the water, sunny sky with puffy clouds and warm sand tones. Dynamic diagonal composition, thick outlines, high contrast, expressive faces, and zippy, high-energy action. Full-bleed image, no borders. No other text or captions.
