Swadclods look like Cyclods in beige yarn bandages (they appear, more or less, to be mummified Cyclods). Sneak Sacks disguised as Swadclods have a yellow eye.
A Swadclod's only form of attack is trying to get a hold of Kirby or Prince Fluff with its wrapper. If it manages to get a hold of one of them, it will throw them against the ground, making them lose many beads. When yarn-whipped, it will reveal one of two enemies, depending on what its eye looks like, either a Cyclod, or very rarely, a Sneak Sack.
