When Flapjack discovers some fresh fruit, which hasn't been seen in years, and Captain K'Nuckles eats it, the two head to an island to get some more. But a mysterious plant man keeps getting in the way. The Dock Hag catches Flapjack and Captain K'nuckles littering and sentences them to community service collecting fish heads. Doctor Barber, however, offers to pay them for the heads, much to their delight, but they soon discover his true intentions for the fish heads.
