Nintendo of America team up with Haylie Duff to celebrate Halloween in another Nintendogs-themed event!

For three days from the 28th of October, 3,600 GameStop locations across the US will host the Nintendogs Tricks and Treats Weekend. If you have a DS and Nintendogs, you'll be able to unlock a free pair of star-shaped sunglasses for your puppies, as well as download a special voice greeting from Haylie Duff.

Additionally, Gamestop and Nintendo are teaming up to donate $50,000 to the American Society for the Prevention of Cruelty to Animals. All together now: "Aaaawww".
