Predapig
(n) - Half Predator, half Guinea pig. when seen in packs they have been known to knock out television reception for up to 5 hours. they feed off the blood of newborn children and the tears of nuns. When consumed they can cure a broken home, and cause nationality transplants. for more information look up Satan's Acolyte.
I'd definitely be less than pleased if the world was under attack of the Mega-PredaPig! >.<
