So many things throwing me violently out of the story. In the first place, the Linnean binomial for tribbles is Polygeminus grex. While that originated in the fan edition of the noncanonical Star Fleet Medical Reference (I have both the fan and licensed editions in my library), it was elevated to canonical status when the relevant illustrations and caption appeared in an Okudagram in either TNG or DS9 (or both). Second, these look about as furry as a Brikar (or as whatever species Darth Maul is). Third, tribbles don't like Klingons any more than Klingons like tribbles; they should have been a mass of shrieking fur, when in that close a proximity to Klingons.
I'm giving it a 5. The 5 that's already up is presumably lonely.
