Sneak Sack is a rare enemy appearing in the game Kirby's Epic Yarn. They only appear in the Pyramid Sands level disguised as a Swadclod and in the beginning of the Cozy Cabin level. A fair number of them appear in certain Beadrix minigames.
Appearance
Sneak Sacks look like white money bags with a red tie on top, a golden eye, and a giant mouth.
Attacks
Sneak Sacks attack by stealing beads and then quickly disappearing. If Kirby or Prince Fluff throws a projectile at a Sneak Sack or unravel one, each gives 100 beads. It gives zero beads if rolled into a yarn ball, however.
