Upon the release of Kirby: Canvas Curse in Japan, the first copies of the game came with a special pink Kirby stylus. A lot of gamers were upset that the same was not offered outside the country. Well, it looks like things have changed. Nintendo of America is now giving away pink styli, presumably the same ones the Japanese got, to anybody who has registered their copy of Kirby: Canvas Curse on their website.
To get your own stylus you'll have to be a My Nintendo member, which is free. You can sign up for My Nintendo on Nintendo's website. You'll also need to register your copy of Kirby: Canvas Curse, by plugging in the registration code that came with the game on Nintendo's website. Finally, you'll need to visit this page to claim your free pink Kirby stylus. Supplies are limited, so hurry up!
