Flapjack and K'nuckles try Peppermint Larry's new candy, "1,000 Pieces of Candy". When they come back for more, having been largely excited by it, they are horrified to discover that the rule is "one per customer forever". Fortunately, Flapjack and K'nuckles, using various disguises, get to taste this amazing new candy several times, ignoring Bubbie's warning about them turning into fish if they eat too much candy. All goes well until they go into the Candy Barrel the next day and discover that they've turned into fish, as Bubbie predicted. They are chased out of Stormalong and Bubbie tells Flapjack that he has to live in the ocean (and pushes K'nuckles down telling him to look after him). They find a place similar to the Candy Barrel (called "The Candy Coral"). Unfortunately, they are labeled "freaks" for refusing to eat candy. The fish advance on them, but they are saved by a group of Mermen who believe that K'nuckles and Flapjack are Mermen as well. They take the two adventuers to their secret lair and attempt to help them "conquer their candy demons". After a long while, the Mermens' treatment works. But as soon as Flapjack and K'nuckles take off their shirts, they discover that they're completely transformed into fish. They are taken to see the doctor, who tells them that they have the fish flu, a result of using fish improperly. They are treated and their legs grow back, allowing them to return to Stormalong. They resume their plan for getting more 1,000 Pieces of Candys, disguising themselves with fake mustaches. But their fake mustaches fall off. Peppermint Larry angrily warns them that they shouldn't have had more than one, but K'nuckles scoffs and points out that they aren't going to turn into fish. Instead of turning into fish, K'nuckles and Flapjack become real people(Fans call them Real-life Flapjack and K'nuckles). They are once again chased out of Stormalong and never seen them anymore. The episode ends with K'nuckles and Flapjack on top of Bubbie (who now has a human face due to having eaten too much candy while they were gone), sailing into the sunset in search of a new home.
- This is the series finale.
- Their is a Fish version of Larry, Lolly, and the Dock hag
- There's a inconsistency with the series due to Flapjack and K'nuckles many times had eaten candies a lot or as much seen in the episode.
