Little is more frightening to an ecosystem than an invasive species. Let's freak out the Earth biologists by introducing Tribbles to ours! We've got a shipment of brightly colored Tribble DNA to combine, fresh off the black market. This craft will produce a mound of small yarn-based Tribbles, and is appropriate for very small fans, as the most threatening thing we'll be using (other than the Tribbles themselves, of course) is safety scissors. Come, have fun with us! Rating: G
