birthday party invitation featuring a giraffe, and a unicorn, and a dinosaur on a birthday cake

Create a fun and lighthearted children's birthday invitation. Focus on using Artbreeder's tools to generate simple, cartoonish versions of a dinosaur, a unicorn, and a giraffe. Avoid detailed facial features by blending more abstract, playful elements to give the characters friendly, animated expressions. Keep the design colorful and lively, with a comic book-like feel, and leave room for adding party details like time, date, and location.
