Bubbles is an awkward looking fellow, with thick glasses, odd clothing, a sometimes hoarse and cracking voice, and a host of physical mannerisms which are unique only to him and his mom that left him. However, despite these shortcomings, Bubbles is typically seen to be very wise, if not intelligent from a scholarly viewpoint. It is assumed that Bubbles endured bullying as a child, as he is very sensitive to being called a "googly-eyed bastard", and often expresses feelings of loneliness.
