This Adventure Time trivia quiz has 170 free questions with answers and covers all ten seasons of Pendleton Ward's series (2010-2018) plus the Distant Lands specials and Fionna and Cake. It starts with the basics of the Land of Ooo, Finn's bear hat and Jake's stretchy powers, then digs into the lore: the Mushroom War, Simon Petrikov and the crown, Marceline's thousand years, Princess Bubblegum's Mother Gum, the Lich, GOLB, and the Gum War that ended the show. About a third of the questions are easy for anyone who has watched a few episodes, a third are medium, and the rest are for fans who know Jake's puppies by name and why Gunter is more dangerous than he looks. Voice-cast and production questions round it out. Every answer has been checked against a primary or encyclopaedic source, and each question links to the page that confirms it.
