Was originally conceived as a show with rejected cartoon characters in detention before it was retooled.
According to show creator Ben Bocquelet, the name Gumball was given before the character was created because it represented the childlike nature of the show.
Gumball, Darwin, and Anais are the only child characters to be voiced by actual kids.
The characters Anais, Richard, and Nicole Watterson are named and based on Ben Bocquelet's own family members.
Many of the supporting characters are actually rejected characters from commercials Ben Bocquelet worked on at Studio AKA before working on the show.
