The art on Walking Dead alone is the stuff of kid nightmares. At least you can censor the language on the rock pins. My 10 year old plays the Metallica in adult mode... The "He's f'd now" comment has played a few times, but only I've achieved the more mom-panic-attack inducing "jack-F'ing-pot!"
The kid knows its a bad word, giggles and knows not to repeat it.
