The Star Trek Tribble Box is now available in the stores. The box contains two videotapes with the two Tribble episodes.
Videotape one: The trouble with the tribbles (TOS)
The Enterprise is summoned to space station K-7 for security duty when the station's security forces are considered inadequate to guard a shipment of valuable grain by the standards of Federation agriculture administrator Baris. A shipload of Klingons stops off at the station as well, which has all parties concerned even more about the grain consignment. Kirk orders stepped-up security, but that only results in some of the crew - including Scotty and Chekov - instigating a massive bar brawl with the Klingons. All the while, the seemingly harmless huckster Cyrano Jones is trying to peddle furry tribbles off to anyone with a few credits, and Uhura buys one and takes it back to the Enterprise, not knowing that tribbles do only two things: eat and breed.
Videotape two: Trials and Tribble-Ations (DS9)
The Defiant is transporting an Orb which the Cardassians are returning to Bajor - the Orb of Time. Also present is a human merchant who was trapped on Cardassia by the Klingon invasion. The merchant is actually Arne Darvin, a disgraced Klingon spy whose downfall came 105 years ago at the hands of James T. Kirk. Darvin uses the Orb to transport the Defiant back to that time period. The DS9 officers must infiltrate the Enterprise and space station K7 to stop Darvin from assassinating Kirk, and at the same time must prevent the timeline from being altered.
