At the top of the Cartoon Style image, the text "Caspian 11 år!"

A big, bright, funny cartoon scene: an underwater birthday bash centered on a gigantic, wobbly, multi-tier cake shaped like rolling ocean waves, dripping frosting and rainbow sprinkles. Eleven sparkler candles form a shining “11” at the peak. A wide-eyed, party-hat-wearing octopus with exaggerated limbs juggles a piping bag, candles, and a slice; a cheeky crab pinches a candle; a pufferfish balloon floats by; and a smiling whale in the back blasts confetti from its blowhole. Exaggerated proportions, thick black outlines, bright saturated colors (teal, coral pink, sunshine yellow, lime green, purple), and whimsical, energetic poses with motion lines, streamers, bubbles, and confetti. Portrait, full-bleed composition with a clean aqua gradient background so the characters pop. Title lettering is big, bouncy bubble letters with a thick black outline and a soft drop shadow, gently arced across the top.

Add one small, cheeky line at the bottom on a ribbon banner: "Wave goodbye to being 10!"
