Create a watercolor vintage-style clip art illustration of a plush hippo, designed for a clipart bundle. The hippo should have a classic plush toy appearance with a charming, vintage aesthetic. Use gentle, muted colors like soft grays, light purples, and subtle blues to give the hippo a warm, nostalgic look. Add details such as round, cuddly features, stitched details, and a friendly, expressive face with small black eyes and a gentle smile. Ensure the hippo has a slightly worn, cozy feel, reminiscent of cherished vintage toys. The overall design should be detailed and inviting, making it perfect for a vintage plush animal clipart bundle
