The front cover of this birthday greeting card features a vibrant, cartoon-style illustration, teeming with elements inspired by Adventure Time and its iconic characters: Finn, Jake, and BMO. The composition is lively and dynamic, with exaggerated features reminiscent of Bill Watterson's imaginative layouts and Hergé’s clear line style.

**Background:**

The scene is set in the whimsical Candy Kingdom, where a bright, azure sky stretches overhead, dotted with fluffy, marshmallow-like clouds. The rolling candy hills in the background are painted in various pastel shades of pink, blue, and green, reminiscent of Winsor McCay’s dreamlike landscapes.

**Foreground Characters:**

- **Finn:** Positioned at the center, Finn is depicted with his characteristic white bear hat and blue shirt. His limbs are playfully exaggerated, similar to Charles Schulz’s character expressions, as he strikes a dynamic pose with his sword raised high.

- **Jake:** To the right of Finn, Jake the Dog is inflated into a giant balloon-like version of himself, his body curving around Finn protectively. His vibrant yellow color is accentuated, and his facial features are comically large, with wide eyes and a huge smile reminiscent of Walt Disney’s expressive characters.

- **BMO:** Nestled in Jake's paws, BMO grins widely, its screen displaying a playful, pixelated birthday cake. The artist could use R. Crumb’s detailed style for BMO’s interface, adding depth to its simplistic form.

**Other Elements:**

- **Birthday Cake:** In the foreground, slightly to the left, is an enormous, cartoon-style birthday cake with exaggerated layers. Each tier is vibrantly colored – strawberry pink, lemon yellow, and mint green – topped with oversized, spiraling candles that twist like tiny roller coasters.

**Text Element:**

- **"Annabelle":** Above the scene, a skywriting banner unfurls across the sky, held aloft by floating balloons shaped like BMO. The text "Annabelle" is written in bold, whimsical letters, each adorned with little stars and sparkles.

The overall composition captures a sense of fun and adventure, combining Gary Larson’s quirky humor with Osamu Tezuka’s dynamic action, creating an engaging visual treat.
