However, "Stargate SG-1" revealed virtually nothing about the Furlings, beside making them the story backdrop of an abandoned site in season 6's "Paradise Lost". Furling skeletons were originally planned to be featured in the episode, but the production of such proved to be too expensive. Jack O'Neill concludes that the Furlings must be cute and cuddly creatures, based solely on their name. In "Citizen Joe", another character equates the Furlings to Ewoks based on their name. The length of time that the Furling nature remained a mystery in the series turned into a running gag. When Executive Producer Robert C. Cooper was asked "Will we ever meet the Furlings?", his answer was "Who says we haven't?". The writers later went on to state that apart from showing Furling technology and legacy, no member of the Furling race has ever appeared on the show. Producer Joseph Mallozzi claimed that more about the Furlings would finally be revealed in "SG-1"s tenth season, which turned out to be an imagined scene from a movie script based on the fictional television series "Wormhole X-Treme!", a parody of "Stargate SG-1" set in the "Stargate SG-1" universe. The Furlings were depicted as Ewok-like, or Koala-like creatures that are destroyed by the Goa'uld soon after making contact with SG-1.
