This big slug likes to crush his foes. He spits some mean thread, too!
— Sulkworm's Cast Description • Kirby's Epic Yarn

They spit wads of gray thread and will fall forward on top of Kirby or Prince Fluff if they get too close. They are immune to the yarn whip, and it takes two projectile throws or the Weight form to defeat them.
