Shunk Wugga was one of the many prospective members of the audience for Probing the Membrane of Science. His only appearance was as Dib's opponent in Battle-Dib. When Dib had tried to meet Professor Membrane while Membrane was at the studio of his show, he was forced to take a series of tests to be in the audience of the show, even though Dib was only trying to talk to his dad personally, not to be in the audience.
