What: The vending machine toy answer to the zombie craze. These mini, brain-hungry guys and girls come in nine different sculpts (including a zombiefied clown, cheerleader, surfer, old woman, etc), with versions that are fully painted as well as versions with just a bit of one-color paint to accentuate details.
When: I picked these up in early 2012
Where: U.S. (at least), sold in toy vending machines
Who: Distributed by A&A Global Industries. Check out their page showcasing this line.
