Or should that be: spell some blocks? Anyway, the point is that a Lego Harry Potter Years 1-4 demo is now available on Xbox Live Marketplace. Finally, you can relive all the great moments from the books. Like when Harry accidentally summoned the Staypuft Marshmallow Man, or when Hermione flew the Millennium Falcon through the Death Star. Okay, so none of those things happened, but it's been like three years since the last book came out. Give us a break.
