Welcome back to Elmore, where the laws of reality are a joke, and family life is anything but ordinary. Whether he's battling an evil fast-food empire, facing off against a sentient AI in love with his mom, or trying to stop Banana Joe from wearing pants — Gumball Watterson drags his brother Darwin, sister Anais, and the rest of the town of Elmore along for the ride. With even wilder stories, bigger twists, and surreal humor, the show is so amazing that they had to rename it!

The season focuses on the misadventures of Gumball Watterson, a blue 12-year-old cat, along with his adopted brother, Darwin, a 10-year-old goldfish. Together, they cause mischief among their family, as well as with the wide array of students at Elmore Junior High, where they attend middle school. In a behind-the-scenes video documenting the production of the second season, creator Ben Bocquelet expanded on the development of some of the characters, and how they are based on interactions from his childhood.
