I am sure that someone here knows the real name for this droid, but I like to refer to him as PuddyKronk. PuddyKronk by jbwolffiv, on Flickr
Puddy? ; No, it's The Tick! ; No, it's flight steward Patrick! ; No, it's Joe Swanson from Family Guy! And the droid's designation is G2-4T. ; His luggage-inspecting co-worker is G2-9T.
