At the top of the Cartoon Style image, "Happy birthday " in big, bubbly hand-lettered letters with white fill, thick black outline, subtle rainbow shimmer, gently arced for a playful feel.

A cute, playful cartoon scene: a plump, sleepy panda with an oversized head and paws, thick outlines, and rosy cheeks snoozes while hugging a giant sunflower like a soft pillow, nestled in a lush patch of towering, bright yellow sunflowers with bold, graphic petals and deep green leaves. The panda wears a tiny tilted party hat; a few floating Z’s drift above its nose. Behind, a vivid, saturated rainbow arches across a clear sky with puffy clouds and tiny twinkling star-sparkles. Add a sprinkling of colorful confetti and a couple of smiling, round bees (also in tiny party hats) gently buzzing around, keeping the mood whimsical and cute. Style: playful cartoon, exaggerated proportions, thick outlines, bright saturated colors, soft shading, clean line art, energetic yet cozy composition.

Color and lighting: sunny, warm highlights on petals; soft, plush shading on the panda’s fur; a cheerful palette of sunflower golds, leafy greens, sky blues, and bold rainbow stripes.

Add a small caption near the bottom on a curved sunflower-yellow ribbon, chunky fun font with thick outline: "Time to party... after a panda nap!"
