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 Jax wears light pink overalls and pale yellow gloves. Their overalls feature yellow buttons, a single lighter pink pocket on the front, and lighter pink roll-up cuffs at the hem. They are usually barefoot. Jax was a mischievous, occasionally flat-out bloodthirsty, laid-back, calm, sassy, impulsive, egotistical, arrogant, sarcastic, brazenly condescending individual who rarely shows any empathy or remorse for others

Pomni is a short humanoid character with a large head, slim limbs, and white skin. Her face has a cartoon mime look, with small light red oval markings under and slightly behind her eyes that resemble blush, She has black eyelids and thick outlines around her eyes. Her pupils usually appear as a red and blue pinwheel pattern Her outfit is in line with a jester. She wears a jumpsuit with a leotard-styled torso, short sleeves, and short, puffy leggings that extend from it. The torso has an inverted color pattern, with blue on the right and red on the left, which swaps on the back. Her sleeves and shorts follow that same pattern. Pomni was high-strung, shy, and tense. In the pilot episode, she is extremely anxious and troubled regarding her predicament, even succumbing to denial and signs of delusion. She's quite clumsy as she tends to accidentally bump into things and people.

Zooble is very grouchy, irritable and quite annoyed, especially when a piece of them happens to be in the wrong place. Like Pomni, they suffer an identity crisis as they don't exactly know what they are, and as a result of this they suffer from body/gender dysphoria, and despite Caine's attempts to provide Zooble new parts, they have yet to find anything they like. Zooble lacks any enthusiasm when it comes to Caine's adventures, more often choosing to opt out of them and do their own thing for the day. Zooble doesn't know what their gender is, because they're questioning their identity, as mentioned before. 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.

Kinger is an alder wood king chess piece. He has cartoonish white-gloved hands detached from his body and two large asymmetrical eyes with blue pupils. Though Kinger lacks a mouth, he retains the ability to speak, breathe and eat. He wears a violet royal cloak with white fuzzy lining spotted with black Kinger is erratic and paranoid, derived from his time in the circus. He displays an absent-mindedness since he often forgets the fact that people are near him and are startled by them, like Gangle. Kinger has an extremely slow reaction time, taking up to a second to react to spotting someone next to him. Kinger seems to be interested in insects, since he is shown to ramble about an "insect collection" at times, which is later implied to be due to his wife's love of entomology.

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 Gangle's emotions and behavior are influenced by which mask she is currently wearing. However, it is revealed that these masks do not completely change her mood, rather they are a literal form of "masking" and are not the sole deciders of her personality. The masks merely change the way Gangle's feelings are presented. When she has her Comedy Mask, her tone, posture, and behavior is masked as pleasant, upbeat, and extroverted

Ragatha's most common outfit consists a collared 1940's cornflower blue dress, patterned with various square shaped patches that are colored a slightly darker blue, though it occasionally appears more purple due to warmer lightingShe has messy, thick, and yarn-like candy-red hair, with each individual strand varying in length, estimating her hair to be roughly at shoulder length. Four pieces of yarn extend right above her eyes, meant to represent her bangsher right eye being a large dark cornflower blue button that's sewn to her face through its four eyelets by a dark gray string, forming an X shape, while her opposite eye is an oval shape that sports a plain jet-black pupil with purple eyelids, with three visible eyelashes sticking out the side.
