Captain K'nuckles

K'nuckles is a washed-up, old sailor who claims to be the greatest pirate the world has ever known. He's always telling over-the-top tales of his adventures and getting Flapjack wrapped up in his high seas hijinks.
- The Alcoholic/G-Rated Drug: Maple Syrup.
- Anti Role Model
- Book Dumb: He can only count to 3. But counting to three allowed him to save all of Stormalong once.
- Cool Old Guy: To an extent.
- Jerk Ass
- Let's Get Dangerous: He's basically a lazy man who talks about adventures but never does them, barely knows how to write and count, and everyone in-universe makes fun of him, but he's capable of carrying Bubbie on his back, winning a fight alone against 100 pirates, escape from a room full of traps, sailing a ship in a storm during a fight against 8-Armed Willy, and stealing wish-candies from a mermaid, among other things and he's 70 or 80 years old.
- Mistaken for Pregnant
- Older Sidekick
- The Pirates Who Don't Do Anything: He claims to be an adventurer, yet he seems to actively avoid doing anything that involves leaving the harbor or performing manual labor. If he ever does go on an adventure, it's usually because Flapjack guilts him into it, or else by sheer accident.
- The Slacker: Once held the title for laziest man in Stormalong.
- Talk Like a Pirate
Bubbie

Bubbie is like an over-protective mother to Flapjack. She prefers the safety of Stormalong to the dangers of the open seas, but Bubbie is always there for Flapjack, no matter what kind of trouble K'nuckles gets him into.
