One million 'Plants vs. Zombies' trading cards head to dentists to help stop 'zombie mouth'

One million packs of limited edition Plants vs. Zombies trading cards are heading to thousands of dentists nationwide starting today as part of the Stop Zombie Mouth Halloween campaign, the American Dental Association and PopCap Games announced.

Each pack of five cards includes a coupon redeemable for a free copy of the full PC or Mac edition of the Plants vs. Zombies game, as well. The cards feature 45 different zombie types and five new characters, each representing a different germ found in a zombie's mouth, created specifically for the campaign.

The Stop Zombie Mouth was announced earlier this month as a way to get kids to either trade in their candy for healthier, non-edible items, or get adults to hand those items out instead of candy.

"Changing eating habits among children is one of the most important yet difficult challenges that parents face today," said Margo Wootan, director of nutrition policy at the Center for Science in the Public Interest. "The ADA and PopCap Games have come up with a fun, clever, and compelling approach that should appeal to young trick-or-treaters this Halloween. This campaign will help children recognize the relationship between healthy eating and healthy teeth, and provide one of the coolest alternatives to sugary snacks yet."

Since the campaign's announcement two weeks ago, thousands of dentists have ordered the Stop Zombie Mouth kits, according to the press release.

The campaign's website also updated today with a new music video, designed specifically to last the two minutes a person should take to properly brush their teeth.
