100 free Hey Arnold! trivia questions with answers — entertainment quiz, new questions added Oct 2026.
42 free Hey Arnold! trivia questions with answers. Hey Arnold! was the calm, jazzy corner of 1990s Nickelodeon, and this quiz is for everyone who still knows what a Stoop Kid is. Forty-two questions cover the fourth-graders of P.S. 118, the boarders at the Sunset Arms, Helga's secret shrines, Gerald's number 33 shirt, Grandpa Phil's war stories and the running mystery of what happened to Arnold's parents in San Lorenzo. There is plenty of behind-the-scenes material too: how Craig Bartlett's clay Arnold shorts ended up on Sesame Street, his link to Matt Groening, why the show was a Nickelodeon first for its voice casting, the 2002 movie that started life as a TV special, the fan campaign that produced The Jungle Movie in 2017 and the spinoff Nickelodeon called too dark to make. Easy questions ask about Arnold's head and Helga's bow; the hard ones want Grandpa's age, Abner's origin and the name of Chocolate Boy's nanny's faraway land. Every answer was checked against Wikipedia's articles on the series, its characters and both films, and each question carries the sentence that backs it up.
