KidRobot Toys Munnies are basically blank vinyl toys you can do anything you want with:
This is the humanoid one. There's also a cow-ish looking one, and other that can only be described as a cartoon-like humanized fox, hippo, baby and teddy bear.
I was definitely up for getting one, but the minis are $10 US and the bigger ones are twice that. Don't be confused by the special marvel hero boxes, the inside is still do it yourself, just colored... EX: The Venom Munny is all black. Paint on the evil face and logo yourself.
