Factual error: Jake takes a huge piece of gold and condenses it down into a small strip. It is then lifted with no difficulty. For the science of the film to work, this would have to be done without losing any of the gold's mass, or they could just get a small piece. As of such, the condensed gold would be just as heavy, if not heavier than in its original form.

Directed by: Norman Tokar
Starring: Roddy McDowall, Harry Morgan, Ken Berry, Sandy Duncan
Continuity mistake: When Jake and Link are watching TV Jake is lying on top of the settee. Link says hi to Jake and the camera switches from Link to Frank. In the next shot Frank sits down and Jake is gone. He had no time to move.
Jake - voice: My name is Zunar J 5 Slash 9 Doric 4 7.
Frank: Uh, Z-Zunar.
Jake - voice: ...Let's just stick with 'Jake', okay?
Trivia: Sandy Duncan has a fear of real cats, so fake cats had to be used when she handles Jake in the film.
