Jax was a tall, anthropomorphic periwinkle[8] cartoon rabbit whose design elements evoked the look of rubberhose characters, despite having actual joints. She had long bunny ears on the top of her oval-shaped head, and her overall build was tall and slender, with a rather long neck. Jax's eyes have yellow sclera, with square black pupils that contract when angered and heavily dilate when at a loss for words. Jax's yellow teeth usually have a flat shape to them, but when her mouth is opened, her teeth appear sharp and jagged.
