Two "tribble" fur balls, made from fake fur, stuffed with foam rubber, one grey and black, the other white, dark grey, and brown, each -- 5in. diameter -- made for "Trials and Tribble-ations" in Star Trek: Deep Space Nine, and also used in the alien bazaar scene in "Rajiin" in Star Trek: Enterprise (2)
Tribbles were the lovably cute alien fur balls that couldn't possibly hurt anyone. That is, until Lieutenant Uhura brought just one of the furry creatures onto the Enterprise. The tribble soon had babies. Then the babies had babies. Before long, it seemed like they were taking over the ship. The script for "The Trouble With Tribbles" was the first professional script by noted science-fiction author David Gerrold. His tribbles became an instant fan favorite and have become synonymous with Star Trek.
