- The Alcoholic/G-Rated Drug: Maple Syrup.
- Anti-Role Model
- Artificial Limbs: both his hands and his body from the waist down have been replaced by functional wooden prosthetics. Some of the episodes' plots revolve around how he lost some of the aforementioned limbs and occasionally his endeavors to recover the originals.
- Authority in Name Only: Revealed in "Down With the Ship" that his only offical naval experience was as a lowly cabin boy and that he appointed himself Captain after sinking the ship. He achieves this rank for real after managing to un-sink the same vessel.
- 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, though as mentioned below, he does have his moments where his badass side shows.
- Crouching Moron, Hidden Badass: He's a cowardly, weak old blowhard, but he DID in fact sail quite a bit in his younger days, and has picked up a few tricks.
- Dirty Coward
- Heavy Sleeper
- I Was Quite a Looker: Claims to have been one before getting addicted to candy in "K'nuckles' Hilarious Problem."
- Jerk Ass
- Hidden Heart of Gold/Jerk with a Heart of Gold: He admits in "K'nuckles' hilarious problem" when he's drunk on candy, that he loves Flapjack and Bubbie so much. Overall, he often comes off as a Jerk Ass, but he has shown he cares about Flapjack, and will feel bad and try to make things right (key word: try) when he realizes he's crossed the line.
- 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.
- Mooching Master: Most of the times he and Flapjack or just Flapjack score a decent amount of candy, K'nuckles takes the lion's share while coming up with some dumb excuse for why he needs it.
- Mistaken for Pregnant: A photographer once had him pose as the perfect example of a pregnant womans stomach.
- Older Sidekick
- Older Than They Look: He looks middle aged.
- Unreliable Narrator: Its difficult to determine just which of his stories are true and which ones are bullshit.
- 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.
- Seadog Peg Leg: His body is MOSTLY wood: two peg legs, two wooden forearms, and a wooden butt.
- The Slacker: Once held the title for laziest man in Stormalong.
- Talk Like a Pirate
BubbieBubbie 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.

- Living Ship: Apparently quite common in the shows setting, as one episode shows several other Sailor/Boy teams having been kidnapped and forced to run a laundromat, with their Living Ship showing up along with Bubbie to save them, among others there's a giant lobster, a dolphin and a giant fat woman.
- Mama Bear
- Multipurpose Tongue: Bubbie's tongue is sometimes shown as being prehensile.
- Only Sane Man: Definitely the most sensible of the three.
- Overly Long Tongue
- Sassy Black Whale
- Talking Animal
- Team Mom
- Third-Person Person: Frequently turns into one of these when pissed.
- Verbal Tic: "Mmm-hmm"
