Splashing Good Times! 💦🎈

A lively, hand-drawn illustration capturing the joy of summer with a giant water balloon piñata hanging above a cheerful picnic scene. Below, smiling friends with water balloons in hand are ready to splash, laugh, and celebrate National Water Balloon Day! Bright, vibrant waves spell out 'Splash into Fun on National Water Balloon Day!' in a playful, hand-lettered style. ☀️🎉
