Image prompt:

- Playful 2D cartoon of a cute little capybara with exaggerated proportions (big round head, tiny paws, chubby cheeks, tiny front teeth), lounging in an oversized plush armchair, sipping tea from a comically tiny teacup with pinky up. A swirl of steam makes loose heart and swirl shapes.

- Festive birthday atmosphere: clusters of glossy balloons (magenta, teal, sunshine yellow, sky blue, lavender) bobbing around the chair, bright confetti and streamers sweeping across the scene in dynamic arcs, a tiny party hat slightly askew on the capybara’s head.

- A small side table holds a saucer and a teeny cupcake with a single lit candle; a few confetti bits have “landed” on the saucer for a cheeky touch.

- Composition: portrait, full-bleed, the capybara large and central; lively, energetic pose (one foot kicks out, eyes gleam with delight).

- Style: thick expressive outlines, bright saturated colors, bold flat cel shading with minimal soft highlights; whimsical, bouncy shapes; clean vector-like finish.

- Lighting: bright, cheerful, soft bounce light with a subtle warm rim light to make the character pop; shiny balloon highlights.

- Background: simple pastel gradient with faint, oversized confetti shapes for depth—keep it uncluttered so the character stays the focus.

On-image text (small, single line):

- “Hap-pybara Birthday!”

Text styling and placement:

- Hand-lettered bubble script with a chunky outline; white fill with teal outline and a soft magenta drop shadow for readability. Place near the bottom or top arc of balloons, sized modestly so the image remains dominant.

Additional notes:

- Keep it funny, cute, and high-energy; avoid realism, drab colors, photographic textures, or busy extra text.

- Aspect ratio: portrait (4:5 or 5:7).
