Pixel Puns: Evil is... a hoof?

Why do people keep saying evil is a foot? I mean, demons are representations of evil, and they have hooves, so evil MUST be a hoof! :P
Speaking of EEEVIIIIL! I just had the most diabolical plan! What happens when a pixel artist discovers Perler beads? The Apocalypse? Yayness and awesomesauce? You decide! XD
Of course, I still need to get my hands ON the Perler beads....
