Sulkworm is a large caterpillar-like enemy which debuted in Kirby's Epic Yarn and later appeared in Kirby's Extra Epic Yarn. He is fairly uncommon and doesn't move around. Sulkworm has two methods of attack, both of which can harm Kirby or Prince Fluff. The first is a silk ball which he spits out in an arc, which can be caught and used against him. The second is a body slam attack which he uses at close range. If Kirby is hit, several of his beads may become trapped inside Sulkworm's body, and be unobtainable until the beast is defeated. Sulkworm cannot be harmed directly using the Yarn Whip, but there are two ways to defeat Sulkworm: throw two objects at him to or use the weight transformation on Sulkworm's head.
Sulkworm can be found in the following levels and stages in Kirby's (Extra) Epic Yarn:
- Sulkworm's name is a portmanteau of the words 'sulk' and 'silkworm'.
