The Adventures of Jimmy Neutron – Boy Genius – Confusion Fusion
The boy genius with the soft-serve hairdo and his geeky buddies indulge in scientific experiments that boggle the mind and put the universe out of kilter in nine 11-minute episodes from the Nickelodeon television series.
Fortunately, Jimmy always sees the errors of his meddling ways and figures out an antidote before the second Ice Age is irreversible or electricity becomes un-invented, depending on the particular jam he's created. Jimmy brings Thomas Edison to the future to back him up in a classroom argument, shrinks his granny to an acerbic talking baby, sends his dad back in time to make good on a lost investment, sprays sunblock into the atmosphere in order to cool down on a summer's day and invents computerized instruments so he and his pals can show off at the school talent show.
