An excitable, adventure-loving boy who was found and raised by Bubbie, the talking whale. Flapjack is very naive and oblivious to danger, thus he's easily caught up in perilous situations. He is also extremely friendly and is often upset when someone does not respect a friendship. Spellbound by K'nuckles' stories of his days of adventure, he sets his sights on becoming a real adventurer just like his role-model K'nuckles. He is gullible enough to believe anything that will help him on his set goal, even if it makes no sense and is completely irrelevant. Flapjack believes that everyone in Stormalong is a friend and often takes them calling him various names and insults as compliments, often leading people (mostly K'nuckles) to believe that he has mental problems. He admires K'nuckles and considers him to be a good friend, though K'nuckles tends to lie to and manipulate him. His catchphrase is "Adventure!" (said whenever he gets excited). He is voiced by series creator Thurop Van-Orman.
