File this under "Scribblenauts seriously appeals to everyone", I guess.
Ever hear of parenthood.com? Well, you have heard of it now, and there aren't any surprises to that site...they literally have resources for people with kids. That's about it. So how they managed to offer a contest like this one is beyond me. I imagine that parents would be busy citing videogames as the reason for obesity or war or perhaps genocide.
Anyways, there doesn't seem like there's much to it. Enter a name and email and you're in the drawing. Three winners will be announced. As long as this copy doesn't like...accidentally get you pregnant or something, there doesn't seem to be any catch.
