Ooblar was the self-appointed "checker of new things to be checked" on the planet Yolkus. He is the brother of King Goobot. The character no longer serves as King Goobot's assistant since he was traded to the Bulgosians for some butter. Ooblar has only appeared in one episode of the show; The Eggpire Strikes Back.
Ooblar is a neon green color. He has two silver robotic arms. The character floats inside of a metal suit and has a pair of red eyes on stalks.
