Pixar-style 3D character portrait of a lovable hippopotamus with a big warm smile and expressive eyes, standing near a calm savanna waterhole at night. Soft moonlight rim-lighting on the rounded face and ears, gentle reflections shimmering on the water, tall grass silhouettes, distant acacia trees, a few fireflies glowing, star-filled sky with a faint Milky Way. Cute heroic proportions, smooth stylized skin with subtle texture, cinematic lighting, shallow depth of field, high-quality animated-movie render, wholesome friendly vibe.
