"Cute and realistic cartoon pygmy hippo character design for stickers. The hippo should be expressive with large, round eyes and soft shading. Illustrate the hippo in various poses and emotions on a white background: sad, smiling, crying, laughing, happy, hungry, pouting, saying 'thank you,' and excited. Each emotion should be clearly conveyed through body language and facial expressions. Soft, pastel tones for the character's skin with subtle shading to make the character stand out on the white background. No harsh outlines, maintain a gentle and friendly look." --ar 9:16
