Tunneler and Leech Woman are absent from this movie, possibly because it was originally written to take place after Puppet Master II, and both of those puppets were critically injured during that movie.
This is the only Puppet Master movie to not feature Tunneler.
This movie was originally going to be the fourth entry in the Puppet Master series, but was replaced with the Totem story-line.
An unused storyline involved a girl buying the puppets from eBay and storing them in the Toyland Warehouse with the demonic toys.
