A playful birthday illustration set against a clear blue sky punctuated by fluffy white clouds. In the center of the sky flies a lively, bright red cartoonish biplane exhibiting a joyful smile and expressive eyes, towing behind it a banner proclaiming 'Happy Birthday!' On the rich green meadow below, an array of animal characters, each adorning a festive party hat, congregates in celebration, waving and cheering animatedly. Multi-colored balloons bob up and down in the breeze, contributing to the cheerful setting and completing the festive ambiance.
