Jimmy is a very intelligent kid, having an impossible I.Q. of 210. In many episodes, his classmates are angered because he is so smart and keeps outdoing them in anything math and science-related. This brain, a source of constant comment, allows him to invent devices that accomplish even the impossible. This usually leads Jimmy causing accidental trouble to Retroville. He designs his wild inventions to help him deal with bothersome chores, but they often end up causing a bigger problem.
