Paranoid Smurf is one of the Smurfs of Smurf Village and was introduced in Smurfs: The Lost Village. As his name implies, he is apparently highly paranoid, and is usually found in his hut staring out from between the shutters. He was apparently overjoyed enough by Smurfette's return to life that he was seen dancing during the Smurfs' and Smurfettes' subsequent party, but quickly lowered his shutters again to resume his customary habit.
He is likely based on (or incorrectly named as) Scaredy or Panicky.
