Blooergard Q. Kazoo - Mac's 5-year old imaginary friend and best friend who resmbles a simple, domed cylinder. Bloo is egocentric and superfical almost to the point of psychotic delusion, which somewhat adheres to the theory that he is basically Mac's ID personality. Bloo is also self-centered and enjoys pulling pranks. However, he still has a good heart and sometimes apologizes for his actions. He loves paddleballs, even though, he can't make the ball hit the paddle (he constantly insists that it's because the paddleball is broken). His full name is "Blooergard Q. Kazoo." He has become increasingly more mischievous over the run of series and his shown to have a bad memory some of the time. He is voiced by Keith Ferguson.
