The blue Smurfs are back, and they're not alone: from the lost village come the new female Smurfs to Smurf Village, where they join Papa Smurf, Smurfette, Brainy, and the other Smurfs in new, funny, and surprising adventures. Time and again, they must defend themselves against the evil wizard Gargamel and his cat Azrael, or the greedy ogres Big Mouth and Egghead.

Who is tougher? To everyone's surprise, Sloppy manages to do a full push-up. Overconfident, he challenges Hefty to a duel. Smurfette asks Hefty not to embarrass Sloppy too much. Unfortunately, Hefty gets distracted just before the end of the course, and Sloppy actually wins. With a trick and a brilliant disguise, Smurfette enables the furious Hefty to have a rematch. The duel begins anew.
