Sneak Sack' are rare enemies appearing in the game Kirby's Epic Yarn. They only appear in the Pyramid Sands level disguised as a Swadclod and the beginning of the Cozy Cabin level. However, numerous amounts of them appear in various levels of Beadrix's missions.
Sneak Sacks look like white money bags with a red tie on top and a golden eye. They also have a giant mouth.
Sneak Sacks attack by stealing beads and then quickly disappearing. If Kirby and Prince Fluff thrown an enemy at a Sneak Sack or unravel one, they will turn into many beads. However, if they wrap it up into a yarn ball, it will give no beads.
