Having received a Priority One distress call from an outlying space station, the Enterprise arrives to find they have been summoned there by a Federation commissioner merely to protect a shipment of seeds meant to sow wheat on Sherman's planet. The planet is also coveted by the Klingons, who are taking shore leave at the station. The trouble arises with tribbles - small furry creatures that seem to multiply without end. However, their fortuitous presence reveals both a problem with the wheat and a traitor on the space station. Written by garykmcd

A fine example of
10 December 2006 | by (United States) – See all my reviews

A bit of a comic relief episode, this is a fine example of the character interplay that makes TOS successful. It's also shows the rich Star Trek universe, with space stations, political characters, space traders, alien enemies, and unusual and desirable (to a point) space creatures. The tribbles themselves are an interesting alien life form, at first glance bewildering to Dr. McCoy, of little practical use to Mr. Spock, threatening to the Klingons, and with an inexplicable life cycle. The episode looks forward to the future of the subsequent series (TNG/DS9/Voyager) in emphasizing political influence and intrigue over the typical episodic phaser displays and bravado, the bar fight excepted. As such it became a great foil for DS9's time-traveling return to K7, and to a lesser degree the animated series' "More Trouble with Tribbles." Silly or no, it's classic trek, and a very enjoyable episode.
