The second chapter of "Puffi" saga is essentially based on Puffetta and the risk for her to become bad: Gargamella infact creates Frullo and Pestifera to attract Puffetta to the bad side. But the frequentation between Puffetta and the two little evil smurfs make them to become good and the story is resolves in a stereotypical way: the good triumph. Nothing special, in final, also if it's considered as a kid movie. Interesting just the scene between Notre Dame's architecture.
