Gumball tells the story of an ordinary suburban family which just happens to live in an extraordinary town. At the heart of this family is Gumball, an excitable and optimistic blue cat with a flair for misadventure. Gumball Watterson has a stay-at-home dad, a mum who sells rainbows, a brainy younger sister, and a goldfish for a best friend. Despite their somewhat unusual appearance, at heart they are just like the rest of us.
