50 free Jimmy Neutron trivia questions with answers — entertainment quiz, new questions added Aug 2026.
Jimmy Neutron started life as Johnny Quasar in a 40-second demo, became Nickelodeon's first CGI movie in 2001, and then ran for three seasons on TV. This quiz covers the whole franchise: the film and its Oscar nomination, the series and its crossovers with The Fairly OddParents, the Planet Sheen spin-off, the video games and the Universal Studios ride. Easy questions ask where Jimmy lives, what Carl is obsessed with and who abducts Retroville's parents. Harder ones get into who voiced King Goobot in the movie, why the character's name was changed, which pop-punk band did the film's theme, how many months the movie took to animate and which physicist Goddard is named after. Every answer has been checked against the Wikipedia articles on the film, the series, the characters and the cast, and each question shows its source once you have answered.
