40 free Mario & Luigi: Bowser's Inside Story trivia questions with answers — trivia quiz, new questions added Oct 2026.
Mario & Luigi: Bowser's Inside Story flips the usual formula. The two heroes spend most of the adventure as stowaways in their greatest enemy, quietly keeping him on his feet while he stomps across the Mushroom Kingdom after the scheming Fawful. Many fans call it the high point of the Mario & Luigi role-playing series, and its jokes, villains and body-part locations are hard to forget. This quiz covers the story from the first outbreak to the last showdown, the heroes and villains, how the battles and controls work, and the making and later remake of the game. A handful of questions revisit the quiz the game itself springs on you in the Flab Zone, where the brothers are tested on what Bowser has just been saying. It is written for anyone who has played the game, with plenty of easier questions for players who know the wider series.
