Create a cute leech doctor character inspired by the animated series "Luntik and his friends". The leech should have a friendly and adorable appearance, with large expressive eyes, a happy smile, and a soft, round body. She should be wearing a tiny doctor's hat and carrying a small medical kit. The colors should be bright and cheerful, fitting the style of the show. The background can be a whimsical nature scene, with vibrant colors and playful elements that match the cheerful atmosphere of the series.
