It appears for the upcoming The Smurfs 2 TNT has made this challenge for Neopia. You have to help save some historical monuments in Paris from the Naughties. In order to save the monument for that week, you have to play two games, Smurfette’s Clean Up Mission and Whack-A-Naughty!
If you sucessfully save the monument, you get a virtual prize. If you help them every week, at the end you will get the grand prize. Good luck!
