The Mrrshan, early in their space exploration discovered a small animal, that bred rapidly. Figuring that they could use it for food, they introduced the small creature into their ecosystems. It was a disaster. The Tribbles ate everything. The Mrrshan eventually developed a bioweapon to use specifically against the tribbles, designed to keep the population in check while growing them for food.

Tribbles (Polygeminus grex) are small, non-intelligent lifeforms originating from Iota Geminorum IV. Known for their prodigious reproductive rate, these round, furry creatures emit cooing sounds while touched, which have a tranquilizing effect on the Human nervous system. Born pregnant, with sufficient food a single tribble can quickly increase its number exponentially through presumably asexual reproduction, bearing an average litter of ten every six hours.

The Tribble bomb is simply a small pod designed with breakaway panels and stasis syetems. The bomb is beamed into the atmosphere above farms and all other ecosystems, Each bomb is roughly 3 meters tall, 2 meters wide, and carries roughly 3000 tribbles. When the bomb hits the ground, tribbles are released, in a 10 meter radius, where they will begin to devour everything in sight. Since the tribbles eat everything, famines will soon occur, with the tribbles covering a massive area in only a few days. In normal distribution, up to 20 bombs are beamed into the atmosphere, depending on how many the ship is carrying.
