Art style: 3D animated cartoon.
Full-length view, the entire group visible from head to feet, standing upright in a row on a grassy farmyard, correct orientation, centered with a red barn, white fence and rolling green hills filling the sides. Four friendly farm animal friends: a plump black-and-white spotted cow with soft brown eyes, pink nose, small curved horns and cloven hooves; a round rosy-pink pig with a curly tail, floppy ears, snout and little trotters; a fluffy cream-wool sheep with a black face, stubby legs and tiny hooves; and a cheerful tan-and-white dog with floppy ears, a wagging tail, pink tongue and paws. All have big expressive eyes, warm smiling expressions and rounded, huggable proportions. They stand side by side under a bright blue sky, sunlit and welcoming.
