Wait do the Romulans know about tribbles?? Cause if they do they would probably use it as a weapon against the Klingons. Like to attack the ship during battle they would just beam aboard hundreds of tiny tribbles and let the chaos unfold? OR if the Klingons board their ship, the romulans could make TRIBBLE DEFENSE BARRIERS TO SCARE THE KLINGONS
Romulan: Commander, the Klingons are boarding the ship!
Romulan: There's twenty of them in the engine room!!
Romulan commander: Very well, unleash the tribbles
Klingons: *high pitched screaming*
