Tribbles (Polygeminus Grex) are small, non-intelligent
lifeforms originating from Iota Geminorum IV. Known for
their prodigiousreproductive rate, these round, furry creatures
emit cooing soundswhen 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 twelve hours. On their homeworld,
Tribble populations are kept in check by a large number of
reptilian predators. These are official license props.
