Three Wise Goblins
As if Skeletons and Cats weren't enough, now here are some goblins getting in on the "Three Wise thingies" meme. (Or is it three Vince Cables?)
Although often depicted as villainous rogues in modern fiction, goblins' earliest folkloric depictions were as helpful (if playful) household spirits, often found doing housework while the dweller slept.
Perch these three inscrutable fellows on a shelf before bedtime (with the help of the sticky pad attached to their posteriors), and don't be surprised if they've dusted it for you by morning! (Or maybe, I dunno, emptied the dishwasher or what have you. No guarantees.)
