a cute and heartwarming Friendship Day greeting card in a watercolor style. The background should feature a soft blue sky with light textures and a grassy green park scene, with trees and leafy plants. Scattered pink heart icons should float gently across the scene. In the foreground, include a sweet cartoon-style little girl with braided brown hair, wearing a blue polka-dot dress and a large blue bow on her head. Beside her, place a teddy bear with a pink bow and a diaper with heart prints, both smiling warmly.
