At the top of the image, "Esmé, you’re 21 now—old enough to party with capybaras and sophisticated cats in tiny hats!"

- In the center of the image, illustrate a comical party scene in a lush garden where capybaras lounge on deck chairs sipping fruity mocktails, and fancy cats strut about in monocles and sparkly top hats. One capybara is holding a karaoke mic while a cat plays DJ with vinyl records.

- Include birthday balloons shaped like the number 21 floating above the crowd, and a disco ball made of yarn spinning overhead.

- One sneaky kitten should be seen attempting to open a bottle of fizzy catnip champagne.

- The entire vibe should be whimsical, playful, and slightly absurd, perfect for a laugh-out-loud birthday card!
