 In an original script, the Rangers were supposed to fight giant Rat  Monsters that Ivan Ooze created. Because the suits didnt work well  enough and looked "too low budget" for the movie, the Rat Monsters  were instead replaced by the Ooze Creatures that Ivan creates in the  film. However, the Rat creature suits didnt go to waste either.  Instead, they would later appear in the "Return of the Green Ranger"  storyline of the Power Rangers television series.
