This ability originating in Kirby: Triple Deluxe gives Kirby a hat in the shape of a circus tent and several circus-based attacks. He can juggle, perform acrobatics, and blow up balloons in different shapes.

Zeke is the tenant in Apartment 101 in Dom Woole's apartment building in Quilty Square of Patch Land in Kirby's Epic Yarn. He offers hide-and-seek minigames, after Kirby decorates his room with the appropriate furniture obtained from the various Treasure chests in the game. Like all the other tenants, he sometimes visits Kirby in Kirby's Pad, and he offers a secret fabric after all his minigames and the main story has been completed.

Bonkers is a large humanoid mid-boss wearing asymmetric armor and wielding what appears to be King Dedede's hammer. He gives the highly-powerful (and rare) Hammer ability, and is the helper of that ability in Kirby Super Star and its remake, Kirby Super Star Ultra. In the episode Goin' Bonkers of Kirby: Right Back at Ya!, he is the unfortunate specimen of a circus show, before he decided to escape and meet Kirby, his personal superhero, in person.
