The Butterman Cometh

Mankind has just been knocked off his perch atop the food chain. The zombie apocalypse is here. But it didn't come alone. Sure, there are legions of hungry mouths, tearing hands, and soulless eyes, but the apocalypse brought a friend. A distant memory that terrified you as a child- remember that creepy cereal mascot in the one commercial with the kids and how he used to chase them around until they found conspicuously placed breakfast bowls in the middle of nowhere? Turns out that guy is really real.
And this time, the kids don't get away. Nobody does.
