Green means GO, but you still want to be careful around this guy!
— Buttonfly's Cast Description • Kirby's Epic Yarn

Buttonflies are common enemies appearing in the game Kirby's Epic Yarn. They first appear on the Flower Fields level and later appear in multiple stages, usually in stages that involve the Spin Boarder form. They usually appear along with Buttonbees. When wound up into a yarn ball they home in on enemies when tossed.


Buttonflies are small, green flies with transparent wings, small black antennae, and a two black lines on their backside.


Buttonflies do not attack. Instead, they just fly around in a set pattern and can easily be yarn-whipped and thrown. When wrapped up in a yarn ball and tossed, it will turn into a single ball that homes in on enemies.
