This was intended to be the final Snix film - involving another possession of Snix, the unveiling of the mysterious sock puppet, the decomposing body of Snix, a scene where the mask levitates and Jim transforming into Snix (without the mask) - but James decided to make three more sequels after this one with on the vast ideas he had to form the Six Snix Flicks.
This was the first movie by James that had a script.
This movie explains Snix's past and recaps the previous movies with Jim narrating.
For most of the still shots in the movie, the camera was stacked on a pile of books - because Rolfe couldn't afford a tripod back then.
The background history of Snix in the film's prologue was created using Mario Paint.
