GHOULIES IV is a straight-to-video addition to the series directed by the notorious Jim Wynorski. It doesn't seem to have any connection to the rest of the series; for example, it does away with the puppets from the previous films and replaces them with dwarves in cheesy costumes. The plot is some nonsense about an alien femme fatale, a crime-fighting cop, and the various characters mixed up in an intergalactic story. It's cheap and cheerful, saddled with lame gags that use old cartoon sound effects and the like, and some very wooden performances.
