Circus Kirby is one of Kirby's copy abilities. It was introduced in Kirby: Triple Deluxe. Kirby wears a cute circus tent-like hat with eyes, a red nose and a curly white mustache. He commonly obtains it from a Clown Acrobot.
Kirby has a wide array of moves and tricks in this form, all relating to the circus. Kirby can juggle bowling bins with some being on fire, jump through flaming hoops, balance on a giant ball and bounce with a trampoline. He also has acrobatic skills in this form with somersaults being an attack. Kirby is very skilled with balloons, with some of the balloons taking on the looks of various Kirby characters and HAL Laboratory's logo. They soon explode though, hurting nearby enemies.
