Star Trek: Captain's Chair Easter Egg - Find the Tribble!

If you viewed the credits, clicked "more" and proceeded through the bios for Simon & Shuster, one of them will challenge you to find the tribble on the Klingon bridge. That is also the hint that the bridge exists.

Once you find your way onto the Klingon Bridge proceed all the way to the main viewscreen, then rotate right until you see the support strut closest to you. Look down at its base, and there lies the elusive white tribble. Click on, it, but don't annoy it!
