The Rainbow Tribble is a Tribble: a cute, round, furry creature that purrs when touched which has a tranquilizing effect on most races. This previously unknown tribble subspecies has evolved a unique defense mechanism: It has the ability to make holographic decoys of itself.

This breed was raised on Risa, its brilliant colors a reflection of the joy seen in all those around it. Petting this breed of tribble helps give you a feeling of the community it's used to, allowing you and your teammates to work together better together in combat. This tribble is unafraid of Klingons or other species that have treated Tribbles negatively in the past.


Petting this breed of tribble provides a sense of community and belonging among you and your teammates. The resulting increased coordination increases team critical strike chance overall.
