Imagine a whimsical park setting on a sunny birthday afternoon, where quirky characters are gathered for a hilarious celebration. At the heart of the scene is a large, cartoonish McDonald's Happy Meal box acting as a stage, adorned with brightly colored balloons tied to its golden arches. Ronald McDonald himself, in his iconic yellow jumpsuit and red striped sleeves, is holding a huge birthday cake shaped like a Coca-Cola bottle, with fizzy bubbles coming out as if it’s just been popped open.

To the left, Snoopy from Peanuts is wearing a tiny McDonald's employee hat and serving burgers to a line of delighted cartoon characters, including Mickey Mouse and Astro Boy. Each burger is humorously oversized, dripping with cartoonishly exaggerated cheese and lettuce. Calvin from Calvin and Hobbes is seen mischievously trying to launch a rocket made out of a Coca-Cola can, with Hobbes watching skeptically.

On the right side of the scene, Tintin is using a magnifying glass to inspect a treasure map printed on a McDonald's napkin, while Snowy, his dog, is licking a spilled milkshake off the ground. Nearby, Garfield lounges lazily on a large Coca-Cola crate, holding a burger in one paw and a Coca-Cola in the other, clearly enjoying the feast.

In the background, you see The Far Side’s cows wearing McDonald’s uniforms and cooking on a grill, their expressive eyes wide with surprise as they flip burger patties. Little Nemo, in his pajamas, floats dreamily above the scene, clutching a bunch of Coca-Cola balloons that lift him gently into the sky.

The vibrant colors, playful characters, and the blend of iconic themes all come together to create a delightful, laughter-filled birthday scene that's perfect for a greeting card.
