She is very small, smaller than Qibli and Winter, and not much larger than Kinkajou and Moonwatcher.
Despite having scales that radiate warmth, her tail lacks the venomous barb of normal SandWings and instead curls to an ordinary point. She has golden wings, talons, and ears, a small head, snout, and claws, and moss-colored, gray-green eyes. Sunny has tawny, unusually bright golden-yellow scales for a SandWing that have been described to look like rippled sunshine.
