Caine is dressed as a ringmaster, sporting a cerise tailcoat with a metallic gold undertone, a black collar with white lining, and a black bowtie. He wears a white undershirt with two red buttons, cartoonish white gloves, and slightly reflective, black latex leggings with matching black tap shoes that appear fused into one continuous form as if they were rendered as a single piece. Lacking most human features, his head is a pair of dentures with pearly-white teeth and red gums. His eyes, which feature a green left iris and a blue right one, float inside the jaw.

She has messy, thick, and yarn-like candy-red hair, with each individual strand varying in length but reaching roughly her shoulders. Four pieces of yarn extend right above her eyes, meant to represent her bangs. Her overall hair seems to be fashioned in a specific manner, appearing to vaguely resemble the 1940s pin-curl haircut, or more specifically, the Shirley Temple haircut. With a blueish dress with dark blue patches and white cuffs.

Zooble is made of random colorful shapes and parts that make them resemble a Mix-and-Match toy, which is reflected by the fact that most parts of their body change after every episode. Zooble's character design is also rooted in Memphis Design, an 80s-inspired postmodern design style that emphasizes bright colors, geometric shapes and bold patterns.

Gangle appears to be made up of four candy-red ribbons that form a humanoid shape. Her face is a white porcelain mask with black eyes and mouth. Her body consists of the main mass of the ribbons that curl, making a spring shape that spirals four times, two ribbons that form her legs, and a single ribbon for her arms (one end is the right arm, while the other end is her left arm). Whenever her Comedy Mask gets broken or removed, her next mask appears, switching to a sad version of the former.

A clear bubble with sharp teeth and pupilless black eyes.

Jax was a tall, anthropomorphic periwinkle cartoon rabbit whose design elements evoked the look of rubberhose characters, despite having actual joints. They had long bunny ears on the top of their oval-shaped head, and their 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 their mouth is opened, their teeth appear sharp and jagged. Almost every time they are talking, their teeth stay closed while only their lips move.
