History Series / EureekasCastle

* OrganAutonomy: Magellan's tail seems to have a mind of its own. Needless to say, this helps contribute to Magellan's clumsiness.

* AxeCrazy: Emma, in the sketch where Magellan gets a cold. She keeps insisting that they need to operate and ends the sketch chasing Batly around with a saw.

* BlindWithOutEm: Batly is even clumsier when he loses his glasses.

* CloudCuckoolander: Most of the characters to some extent, but especially Mr. Knack.

* DontCallMeSir: One of the [[RunningGag running gags]] involves Mr. Knack insisting on the others calling him Nick, causing them to reply, "Oh… Nick Knack," to which someone else (usually one of the mice) will chime in and sing, "Paddywack, give a dog a bone!"

* SickEpisode: Magellan gets a cold in one sketch, while in another Bogge gets the flu and Batly [[PlayingSick plays sick]] to get the same amount of attention. The following three sketches also relate to health; one is a "Them Bones" music video, one involves a bird getting laryngitis, and one is about one clay guy PlayingSick to get out of building the boat.

* SongParody: "Put It on the List" in the Christmas special is sung to the tune of "I've Got a Little List" from Gilbert and Sullivan's ''Theatre/TheMikado''.

* SuperHero: Superdragon(dragon-dragon-dragon) and ({{Fanfare}}) Batboy, the imaginary superheroes who are [[CaptainErsatz almost the same]] as Franchise/{{Superman}} and Franchise/{{Batman}}.

* RefrainFromAssuming: It's not a [[Franchise/TheMuppets Muppet]] production, despite its similarity to ''Series/SesameStreet'', not to mention Pam "Grungetta" Arciero performing Quagmire and Brian "Barkley" Muehl doing Bogge and Mr. Knack. Also, one of the scriptwriters for the series was Louise Gikow, who penned a number of ''WesternAnimation/MuppetBabies'' and ''Series/FraggleRock'' children's books and had been a writer for ''Muppet Magazine'' as well; she also co-created ''Series/JohnnyAndTheSprites'' with current-generation Muppet performer John Tartaglia.

* IWantSong: "Put it on The List" sung by Bogge and Quagmire in the Christmas episode to the tune of "As Someday It May Happen" from the Creator/GilbertAndSullivan opera ''Theater/TheMikado''.

The show also aired cartoons, often American dubs of UK or European exports, including ''WesternAnimation/{{Roobarb}}'', ''WesternAnimation/TheShoePeople'', ''WesternAnimation/{{Towser}}'', and ''WesternAnimation/JamesTheCat''.

* NoAntagonist: Seeing that one of the main themes of the show is learning to cooperate with others in spite of differences... The Moat Twins sometimes come close, but even so, the rest of the characters consider them as friends.

* IdiosyncraticWipes: A variation where it's done between segments instead of between scenes. They involve an animated version of the castle's winding key, which may or may not turn a couple or so times before going to the next segment.[[note]]There's even a version where the key doesn't stop at all, and goes right to the next segment.[[/note]] The half-hour version also features a second one that features one of the castle's towers with the winding key, similar to (but not quite the same as) the show's AdBumpers.

* IneptMage: Eureeka usually ends up failing her spells except in the bumpers. One example: she tried to make an ice cream float with magic and ended up with the ice cream floating in the air. She does admit that she's still learning, however.

As of April 2021, 26 episodes of the show's half-hour configuration are available to stream on Creator/Paramount+

* IWantSong: "Put it on The List" sung by Bogge and Quagmire in the Christmas episode

* AdBumpers: Just like ''Series/{{Pinwheel}}'' before it, this show has it's own ad bumpers, unlike most of Nick Jr.'s other shows. They involve a castle tower with the winding key, and after winding up three times, it would do something random[[note]]Such as cutting into a scene featuring the Slurms or the Giant, or simply featuring other various things seen on the show.[[/note]], followed by showing the title.

* WeWantOurJerkBack: Happened with both Batly and the Moat Twins when a couple of Eureeka's spells accidentally made them nice

* SneezeOfDoom: Magellan's sneezes shake the whole room and himself due to his size. It's so powerful, it actually once broke one of Eureeka's spells.
