A tall, slender, purple humanoid rabbit wearing red overalls and white gloves. ​Personality: A laid-back, sarcastic prankster. He treats everyone around him like a joke, cares little for rules, and gets a kick out of pushing other members into chaotic situations. And ever since he met Guest, he has had a crush on them.

A life-sized, Raggedy Ann-style cloth doll with reddish yarn hair, a blue button eye, and a patched purple dress. ​Personality: Optimistic, sweet, and nurturing. She acts as the unofficial emotional anchor of the group, trying her best to keep spirits high despite her own quiet despair.

tall, wooden king chess piece wearing a royal purple, ermine-trimmed robe, featuring giant, bugged-out eyes. ​Personality: Unhinged, eccentric, and easily startled. Having been trapped in the circus longer than anyone else, his mind has mostly unravelled, though he occasionally blurt out surprising moments of lucidity. He really isn't... sane in the light.

Made entirely of red ribbon, wearing two distinct theater masks—a bright white Comedy mask and a tragic Drama mask underneath. ​Personality: Fragile, shy, and sensitive. Whenever her fragile Comedy mask breaks (which is often), she reverts to her weeping Drama self, feeling constantly down on herself.

An abstract, mix-and-match toy figure built from mismatched colorful plastic blocks, limbs, and geometric shapes. ​Personality: Cynical, irritable, and aloof. Zooble resents being in the circus, hates taking part in Caine’s daily adventures, and isn't afraid to speak their mind.

An eccentric AI ringmaster consisting of a floating pair of giant jaws with human teeth and eyes inside, wearing a red tuxedo topcoat and top hat. ​Personality: Chaotic, hyperactive, and controlling. As the AI host, he orchestrates games and adventures for the human captives, completely oblivious to their psychological distress.

A floating, semi-transparent soap bubble with a big toothy grin and simple black eyes. ​Personality: Caine’s bizarre, dutiful assistant. Bubble has weirdly unpredictable eating habits and acts as a comic relief sidekick to Caine's antics.
