Book excerpt: When Natural Smurf, Slouchy Smurf, and Snappy Smurf arrive at The Smurfs village as The Smurflings, all their newfangled ideas start to turn things upside down. Whether it's back-talking Grouchy Smurf, outsmarting Jokey Smurf, wearing their own clothes, or making up their own music, it looks like nothing will ever be the same. But the biggest change is yet to come -- and it looks like Gargamel is behind it!
