The 16-foot tall Tyrannosaurus Rex robot from the first film was reused for this sequel. In the original movie, the robot had frequently broken down and performed so poorly that its use was limited to only a few shots. Despite budget constraints, Magical Media Industries did manage to improve the robot T-Rex so that it could be used more extensively for the battle scene in which the dinosaur fights the forklift. However, the robot was still ill-suited to stunt work (such as the shots of the creature ramming the forklift), so miniatures and hand puppets were again used frequently, as in the first film.
The Deinonychus from the first film were replaced by Velociraptors in the sequel. However, the exact same Deinonychus costume molds from the first film were used to create the bodies for the Raptor costumes; only the heads/necks were changed to reflect the longer neck and snout that distinguish the two dinosaurs. Close-ups were achieved using puppet heads with mechanical devices.
