The titular character of The Amazing World of Gumball, he “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.” (Fandom Wiki)

TL;DR an amazing cat
