Sulkworms are enemies in Kirby's Epic Yarn. They are gigantic, fat, green, slug-like enemies. Sulkworms have yellow and orange dots (or you can say holes) in their bodies and a yellow and red antenna. Sulkworms have a squiggly green mouth and orange and red button eyes with green pupils. Sulkworms are rare enemies, for they only appear in Big-Bean Vine of Grass Land, and Castle Dedede of Dream Land. They attack by spitting chunks of thread at Kirby and Prince Fluff. They will also fall forward on the heroes if they come too close to it. Both of these attacks can cause the heroes to take damage if they are hit by them. Sulkworms are immune to the yarn whip and can only be defeated by throwing two yarn ball projectiles at it or by transforming into the Weight form above it.
