Standing tall and broader than average, it is clear that Jokull stems from a draft, but mixed lineage. His nose rounds into something akin to Roman, but not very clearly so. His neck and shoulders appear sturdy, as well as his legs, which end in quite a bit of feathering. His creamy-white mane and tail are thick and relatively long, a sharp contrast to his dark bay skin.

Covering Jokull's body from about his forehead, along his neck and shoulders to his knees, he consists of ice scales, whereas his nose, underbelly, and lower legs are warm and fuzzy as one would expect from his type.

Jokull's legs are covered in tribal swirl tattoos, but unlike his father's ones, his are glowing golden. His front right and hind left leg also have a low, metallic golden sock, the same color as the slightly off-center star and snip on his face, but these do not glow as his tattoos do.

Jokull tastes the fruit of his ever-present happiness induction: since nobody he meets could stay sad or angry for overly long, he has little to no negative experience in his life. He is joyful, endearing, and caring. Another way to describe him might be young or naive, and cuddly.
