The FIRST time I watched Star Wars, we went as a group, my brother, my sister-in-law(to be), her 3 brothers, eldest brother's girlfriend, etc. Littlest brother was only 8 years old. He dubbed the garbage room monster "The Great Googly-Eyed Thing", and so it has remained, lo these many years hereafter. Don't care what Mr G. Lucas calls it.
I'm happy to see that Sheldon appreciates a good monster when he meets one!
