Orbitfly is a small flying button enemy from Kirby's Epic Yarn and Kirby's Extra Epic Yarn. It is the last of the four different types to be discovered (the other three being Buttonfly, Buttonbee, and Buttonbug) and is found in space stages like Stellar Way and Outer Rings. They can be seen flying in various formations in large numbers, prompting Kirby to shoot them down with either the Rocket or Star Shooter transformations before they crash into him. Defeating every Orbitfly in a particular formation will yield a larger number of beads then defeating them individually.
