The "Sack Man" is one of the seemingly infinite alter-egoes of the legendary Bogeyman and much like the Monster Under The Bed is a specific form the creature is said to take - however unlike most versions of the Bogeyman the dreaded "Sack Man" may have roots in a very real and tragic tale of old. The "Sack Man" is envisioned as an impossibly ugly and skinny old man carrying a large sack who wanders the land searching for "naughty" children - whom he is said to capture and stuff in his bag before spiriting them away to a grisly fate (many tales say that the "Sack Man" eats his young victims).
