The Amazing World of Gumball tells the story of an extra-ordinary suburban family who just happen to live in an ordinary town. Dad is your regular 6'4" pink rabbit who stays home while Mom works in a rainbow factory. Their kids are pretty standard too- there's Gumball, a blue cat with a giant head, Anais, a 4-year-old genius bunny and Darwin, a pet goldfish who became part of the family when he sprouted legs. At the heart of The Amazing World of Gumball, who faces the trials and tribulations of any 12-year-old-kid, like being chased by a rampaging T-Rex, or dressing as a cheerleader to impress the girl of his dreams.

When Gumball and Darwin decide it's time they join a crew, they agree that the coolest posse in Elmore is the Senior Citizens. They do everything they can to fit in with them, going to extraordinary lengths to prove themselves worthy of running (well, walking very slowly) with them.
