Imagine a vibrant and whimsical garden bursting with life, in a style reminiscent of Bill Watterson's playful lines and Gary Larson's imaginative flair. At the center of the scene, there is an oversized, multi-layered birthday cake, each layer a different bright pastel color, topped with a cascade of whimsically exaggerated flowers and a large, sparking numeral '90' candle that towers over the cake.

The background is a lush garden with oversized flowers in bold, primary colors, akin to the simple yet bold palette seen in Charles Schulz's Peanuts. Each flower has an expressive, cartoonish face with exaggerated features, smiling widely as they seem to lean towards the cake, almost as if they’re part of the celebration.

Floating above the garden are a cluster of oversized, shiny balloons in the shape of numbers and letters, spelling out "Happy 90th Birthday!" in a swirling array of colors, akin to the playful movement you’d see in Winsor McCay’s Little Nemo panels.

In the foreground, add a small gathering of cartoon animals dressed in tiny party hats. They can be inspired by Walt Disney’s charming character designs—perhaps a rabbit in a polka dot dress and a turtle with a bowtie. They are gathered around the cake, looking up at the towering '90', their eyes wide and exaggerated like Osamu Tezuka’s iconic manga style, creating a delightful sense of scale and excitement.

The sky is a rich, bright blue, dotted with fluffy, exaggerated clouds that echo Hergé’s clean line style, providing a perfect backdrop to the joyful chaos below. The entire scene is enclosed in a circular border, much like a window into this festive, cartoon garden world, inviting the viewer to join the celebration.
