According to Yahoo Finance, Nintendo and GameStop will contribute $50,000 to the American Society for Prevention of Cruelty to Animals as part of their "Nintendogs Tricks and Treats" Halloween event. In 3,600 GameStop stores across the country this weekend, Nintendogs owners can recieve virtual star-shaped sunglasses for their Nintendog. The game promotion runs from October 28 to October 30, but frankly, the ASPCA contribution seems a bit more notable. Good for Nintendo and GameStop for helping to fight animal cruelty.
