Matchu,
Tribbles are from the original Star Trek series, from the "Trouble With Tribbles" episode. Tribbles are round balls of fur that coo and purr and lull the humans around them into a calm, peaceful state. Tribbles hate Klingons and screech when they are near one. Vulcans think tribbles are useless because all they do is eat and make more tribbles - Vulcans are pure logic and no emotion, so they aren't affected by the tribbles' soothing nature.
One tribble was bought by an unknowing victim on a trading station and brought aboard the Star Ship Enterprise, before anyone knew that they reproduced asexually and therefore prolifically. They also ate everything in site. Bones (the ships doctor) said that they were born pregnant, so they had quite the head start. At first people thought they were cute. But the more they were petted and the more they ate, the faster they multiplied. Soon the whole ship was overrun by thousands of tribbles. They exploded exponentially. Tribbles, tribbles everywhere. No one knew what to do.
Unfortunately, the Enterprise was carrying a full cargo load of Quattro Triticale, a special grain bred to grow well in... oh, shoot. Can't find the word. You know, when there is no rain and the earth is dry and won't grow things and people starve? What's the word????? Help me out, here. Well, anyway, the grain grows in those conditions.
Anyway.... the cargo hold is full of quattro triticale, and a tribble finds its way into the cargo hold. It starts eating and multiplying, and before long there are hundreds of thousands of tribbles in that cargo hold, and no grain. They ate every last kernel. And made as many more tribbles as could possibly fit in there. Packed tight. Needless to say, the ambassador to that country was pretty pissed off about his grain.
I can't quote the Star Date from the beginning of the episode, so I guess that makes me a Trekkie-Wannabe, not the real thing. Thank goodness. Lol....
You are now an expert on Tribbles.
