As a calf he's longer than he is tall, gangly, and a warm steeped-tea brown that slowly darkens to shades of amber, through brown, to espresso as a fully grown adult. He's still growing and won't be mature until he's two years old. Once he's reached that milestone his body will begin to pack on weight (notably across the shoulders) until his profile is more wedge-shaped and his head is forced down, as if he is ready to charge at the drop of a hat. His legs are cream-colored until the shoulder / hip, and the same cream tone gradually appears across the top of his head while his horns grow in. These things are hefty, curved, and extremely dangerous.
Note: Images depict him as an adult & size stats on profile aren't final size.
