One of the leading cast of the series, was the most oddly apropos, particularly the role of Donnie Thornberry. The reason Flea, a.k.a. Michael Peter Balzary, is considered an appropriate choice to play the role of Donnie, is because the character is slightly based on how Flea earned his nickname. The origin for Flea's nickname was when he was a child, he had an inability to sit still, and the nickname has been stuck since. And what better person to play a wild and overly-active character then someone who was the "Donnie" of his own family.
