At the center, oversized bubbly hand-lettering: "Color outside the lines—it's your birthday!"

- Surround with a cute, playful cartoon scene: a giant coloring-page birthday cake in thick black outline, while adorable anthropomorphic crayons, markers, and a paintbrush (big eyes, tiny limbs, party hats) joyfully doodle rainbow squiggles that spill well beyond the cake’s lines.

- Add swooping streamers, confetti, and dashed motion trails forming whimsical lines that loop around the characters like a conga line.

- Style: exaggerated proportions, thick outlines, bright saturated colors, energetic poses, flat cel-shading.

- Background: soft pastel gradient with sparkles; keep composition clean and text-first.

- Important: include only the single line of text above; no additional text.
