Idea Hole

Speaking of things that are horrible – I had this idea pop into my head the other day, and I have yet to find some sort of use for it: Sky Leeches.

Swarms of buzzing sky leeches settling upon the land; clouds of them laying waste to cattle and poultry; black, sloppy hives hanging from eavestroughs.

Their natural predators? Possibly Air Pirates or The Great Polynesian Winged Turtle.
