The Three Caballeros, Xandra, April, May and June visit Camelot to go through "hero training" from King Arthur himself. Meanwhile, Sheldgoose breaks into the Caballeros' shack to steal the Spark of Life.
- Actor Allusion: King Arthur is voiced by John O'Hurley, who previously portrayed King Arthur in Spamalot, as well as voiced King Neptune on Spongebob Squarepants.
- Sir Galahad is a frog voiced by Matt Danner with a voice nearly identical to his Kermit the Frog one from Muppet Babies (2018).
- Aw, Look! They Really Do Love Each Other: Panchito says this nearly word for word when King Arthur and his knights reconcile.
- Bear Hug: The Caballeros receive a rather literal one from the Bear Rug when they return to the land of the living.
- Big Damn Heroes: For once, the nieces are the heroes of an episode, as they have to get everyone out of a mess they themselves created.
- Black Comedy Burst: The death of the Smartphone salesman after Merlin tosses June's phone into his magic fire.
- Crouching Moron, Hidden Badass: Ari and Sheldgoose put up a decent fight.
- Dartboard of Hate: Sheldgoose finds one of him inside the Caballeros' shack.Sheldgoose: And that's just mean.
- Family-Unfriendly Death: The nieces kill the dragon they accidentally summoned by throwing its summoning scroll into the fireplace to burn it. It apparently also works on anyone relating to whatever's thrown into it, as a smartphone tech expert disintegrates after Merlin throws June's phone into the fire.
- Furry Confusion: Bors the Younger is an anthropomorphic basset hound, who looks very similar to the non-anthropomorphic hound that urinates on the staff Felldrake's trapped in.
- The Gambling Addict: Merlin, whom Arthur won't let play any games because of his "problem". When the nieces distract him with a smartphone game, he refuses to let anything come between him and the promised (virtual) riches for playing, not even the mess the nieces created.
- Gender Flip: Kay, who is male in the Arthur myths and in The Sword in the Stone, is female here.
- Immortality Inducer: The Grail grants eternal life to Arthur and the Knights of the Round Table.
- Magical Incantation: The nieces read a magical poem that summons Tyrone the Dragon.
- Modesty Towel: Ari wears one for most of his scenes, as Sheldgoose broke in while he was taking a bath.
- Nice Job Breaking It, Hero: The Triplets summon a dragon out of boredom.
- Reactive Continuous Scream: One between Ari and Sheldgoose when Sheldgoose attempts to steal back the Spark of Life. Ari, being Ari, ends up breaking into a random bout of opera before he attempts to attack Sheldgoose.
- Rousing Speech: King Arthur's entire "training" is mostly him shouting rousing motivational speeches and plugging self-help books. When the Caballeros point out the flaws in his methods, the other Knights declare mutiny on him.
- Running Gag: Arthur's motivational speeches all deal with parts of the word "Camelot" and his name. Eventually, Xandra and Donald get annoyed.
- Shout-Out:
- While the Arthur, Merlin and Kay who appear here are nothing like their incarnations from The Sword in the Stone, the episode still features a clear nod to the movie when April, May and June look through Merlin's magic scrolls. They find a spell that turn you into a fish, and one that turns you into a squirrel. And one that makes you twelve percent fatter.
- Merlin himself is a combination of the classic Merlin, along with elements of Professor Owl from the Adventures in Music Duology and the Sing-Along Songs series.
- Arthur shares a strong resemblance to King Richard from Robin Hood (1973).
- Tempting Fate: After Donald's (justified) complaints has turned the Knights of the Round Table against Arthur, José remarks "I do not see how this situation could get any worse." Moments later, the dragon attacks.
- Urine Trouble: As Felldrake can't get into the cabana due to the magic barrier, he has to stay outside and so his staff is stuck into the front lawn. It isn't long before dogs come sniffing.
- Wall of Weapons: DoubleSubverted. Arthur leads the Caballeros to his armory, but when he pulls the curtain, it's just more of his self-motivation books and merchandise. After the others complain, Arthur then opens a wall just behind it, revealing the real armory.
- Wham Episode: Sheldgoose didn't get the Spark of Life... but he did get the Caballeros' magic amulets.
