Bloo

Blooregard "Bloo" Q. Kazoo is one of the main characters from the original series . He is a blue, cylindrical imaginary friend created by Mac at the age of three. He is often very self-centered, egotistic, and narcissistic, as well as having a knack for getting in trouble. Despite his selfishness and egotism, though, he still has a good heart and cares deeply for his friends, even if he doesn't like to show it.

To date, Bloo's only appearance in a Christmas production was, of course, the series' Christmas episode, "A Lost Claus".
