You're Just a Wild Man! | Clarence | Cartoon Network

Sumo starts acting super smart after some new classes, and Jeff is loving it! But Clarence’s goofy antics might bring the old Sumo back... Season 3, Episode 28: "A Sumoful Mind" In a world of noise, Clarence is a jar of sunshine, pure and simple. He sees the world only in his favourite colours: goofy grape and neon green. Clarence values his friends Jeff and Sumo and his mother Mary more than gold. No matter what happens, good or bad, nothing brings Clarence down.
