Keema (Dennis Patrick), a resplendent, friendly, and helpful 'golden man', and a repulsive, unpleasant and belligerent frog-like alien choose the Robinson's planet to fight a war on behalf of their respective planets, pressuring the space-castaways (only Smith and the women, Will, Don and John being off somewhere doing important science-stuff) to choose sides. The episode is particularly juvenile, with a mine-field portrayed by beach balls, Christmas lights decorating 'barb wire', and a frog costume with a rigid head that doesn't move when the creature is speaking. Production continue to be sloppy - special-effects explosions occur some distance from the supposedly detonating prop and gadgets recycled from earlier episodes are minimally disguised (such as the little grenade tossing robot or the frog-alien's ship). On the plus side, some of the exchanges between the robot, Smith, and Keema are amusing - the robot comments that a 'ham' is an appropriate gift for Smith (perhaps a dig at Jonathan Harris flamboyant acting style) and the gilt-alien comments on how friendship is often repaid with betrayal (which pretty much sums up the Doctor's behaviour in most episodes). Considering the plot's 'message' is 'don't judge a book by its cover', the story takes an odd turn at the end, almost as if the writers themselves didn't actually believe in the moral (perhaps appearances are everything in Hollywood...). The Jupiter 2's bottomless cargo-hold now appears to have contained WW2 era webbing and packs.
