I can not find Clumsy SmurfBy
As stated in the Clumsy Smurf section, Clumsy can only be found if the village is at least on level 20. If the village has reached level 20 and Papa Smurfs quest have been done regularly, he will ask to send two Smurfs away for 24 hours. Once they return to the village, the two Smurfs will bring Clumsy Smurf back to the village with them. If there is still an outstanding quest from Papa Smurf after reaching level 20, this task has to be completed first before he will give the task that brings Clumsy Smurf to the village. To get Clumsy Smurf right after the village has reached level 20, Papa’s task from the previous levels (i.e. the two to five new ones that come with a little story after a new level has been reached) have to be completed first, so if they have been neglected for a while it might take some time to complete all the outstanding tasks before Clumsy can enter the village.
