Between this and the Mario hat available to Platinum-level Club Nintendo members, Nintendo gamers may have the next two Halloweens in the bag.
So far, the hat is only available for online and in-store customers of GameStop in the US and EB Games in Canada, but we'll keep you posted if it reaches anywhere else. Scribblenauts hits North America on September 15.
EDIT: Looks like it'll be hitting EB Games in Australia too. Hooray!
