For a solemn cartoon birthday theme, visualize a scene set against a subdued, dusky background. At the center, an extravagant electric car with muted balloon decals stands with its doors open, setting the stage for an intimate celebration. Beside the vehicle, a small round table showcases bottles of artisanal beer with custom labels celebrating the event. In a corner, two curious felines peek out from a tastefully decorated cage adorned with soft birthday streamers, contributing an element of whimsy to the generally austere ambiance.

Generated with these themes: Tesla, Beer, and Cats in cage.
