Here's my post on the episode.
Maybe Bob would have done better if he'd been describing a Wookiee rather than an Ewok? But in any case, the fix was in: the Star Trek clues were much easier to get without referencing anything to do with Star Trek than the Star Wars ones were. I mean, "future"? And Donald got too much in his own head sticking with Star Wars clues even after Ellie said she knew nothing about Star Wars; how about trying to get her to guess "Revenge" by talking about the concept? Or the show, on ABC, called Revenge?
