The Smurfs: The Adventures of Johan and Peewit (1980)

The Smurfs: The Adventures of Johan and Peewit is an American-Belgian animated musical films developed by Walt Disney Animation Studios that was first released in Europe in 1980 and later in America in 1988, when it was dubbed into English. Because it was developed by a production company other than Hanna-Barbera and it does not tie in with any of the stories featured in the Smurfs cartoon show, it is considered a "non-canonical" Smurf story.
