If you're a long-running StarCraft fan, chances are you'll remember this cute infestor that sounds like a 4-year-old making raspberry sounds. It wasn't a unit that ever actually existed: it was part of a parody animation series called StarCrafts.
But then the animation series went viral. Blizzard got on board, and then the mass of fans got so large that someone eventually started working on a mod. And as of today, you can now finally play StarCraft 2 the way it should be played -- with pudgy marines, zerglings you'd keep as a pet, and infestors that sound like 4-year-olds.
