He attends Elmore Junior High in the seventh grade with his brother Darwin, who is 10 years old . Often finding himself and Darwin in various antics which end up getting them into trouble, episodes in the series' first season characterized Gumball as well - meaning in his actions, but with naive tendencies; throughout the show's progression, he has since established himself as a more serious character capable of logical thinking and prone to sarcasm . </P> <P> Despite his rambunctious behavior and occasional lapses in judgement, he is ultimately a loyal, straightforward, and kindhearted person at heart . A recurring theme throughout the series is his crush on his classmate Penny Fitzgerald, who in turn shares the same feelings for him . They initially struggle to properly express their feelings for each other until the episode "The Shell", where he finally works up the nerve to express his feelings to her after she reveals her true form, and they begin dating . In the premiere of season 3 it is revealed that Gumball and Darwin are part of a small fraction of people who don't age past a certain point, which by the end of the episode causes them to regress to a point slightly before puberty . His middle name was supposed to be Christopher, but Richard confused it for Tristopher and it stuck . Gumball is a very imaginative person . Despite his mediocre academic performance, he can be surprisingly brilliant when it comes to formulating all sorts of mischievous schemes . This side of him can be seen in episodes such as "The Plan," in which he quickly formulates a basic outline to he and his siblings plan to "save" their mother, and in "The Scam," in which he forms a crafty scheme that will allow him to cleanly heist the town's candy effortlessly . Such a side may also suggest Gumball is smarter than he lets on, as hinted by his expansive vocabulary, cooking skills, and ukulele skills as well . </P>
