This 8-inch interactive Tribble responds to your gentle strokes with soft, tranquilizing coos, and lets out a little trill every once in awhile just to remind you that it's there - and it vibrates too. Use the free app to ask your Tribble to search for Klingons, to guard your stuff, or even to SCREAM ON COMMAND at your friends, family, and co-workers. Add this Tribble to your personal collection or gift it to the Star Trek fan in your life! Officially licensed.
