The episode also had some of the show's most effects intensive scenes done yet. Animatronic versions of both the small and large Polymorph creature versions were created. The small version was voiced by production manager Mike Agnew. The larger model, which was prone to tipping over, collapsed before the final shot. Blue screen was used to shoot the creature and added to existing footage of the crew. To achieve the Polymorph morphing into all the different objects the traditional locked-off camera and jump-cut procedure was used. The newly introduced Bazookoids provided more video effects as two heat-seeking laser bolts were fired and ended up chasing the Cat. The heat-seekers were given sound effects borrowed from the lightsabers of "Star Wars".
