Schemer Smurf is a Smurf character that appears only in the animated version of The Smurfs And The Magic Flute. He is one of two Smurfs, the other being Southy, who was sent by Papa Smurf to track down the magic flute. He first appeared in Peewit's bedchambers in a first attempt to retrieve the magic flute, then later appeared to keep track of Matthew McCreep's whereabouts as he used the magic flute to steal people's valuables.
Schemer is the name used for the character in the United States English dub of the movie. The particular dub also has him sounding like Hefty Smurf from the 1981 TV series (since Hefty has a completely different voice in the movie), even though Schemer is not voiced by Frank Welker.
