On a mission to a station 
we ended up in the bar 
There were Klingons and Cyrano, 
a trader who had travelled far 
Uhura couldn't resist 
the fluffy thing he had for sale 
So she brought it to the Enterprise, 
which proved to be a big mistake 
Trouble with tribbles, multiplying rapidly 
Overwhelming the starship, cute little enemy 
Meanwhile at the station  
similar problems 
The cargo being eaten  
and obviously poisoned 
But Klingons and tribbles  
don't like each other at all 
So a spy was revealed and the plot as well, 
but what to do with every furry ball? 
Trouble with tribbles, multiplying rapidly 
Overwhelming the starship, cute little enemy
